Unblock auto-releases

Last time this ran, GoReleaser built an artefact with the wrong version
- it didn't bump it correctly. It was meant to build 0.1.0-alpha.33, but
it built 0.1.0-alpha.32 instead:
https://github.com/dagger/dagger/runs/4860126130?check_suite_focus=true#step:7:94

This new approach is a simpler and more explicit tag bump by leveraging
the semver-tool directly. A link to this utility is included in the
comments. We version it in this repository so that it is all
self-contained.

We also use the gh CLI tool directly, instead of a GitHub Action that
hides the implementation detail behind Typescript. We now have two very
simple gh CLI invocations that do all that. While we still use the
https://github.com/lewagon/wait-on-check-action GitHub Action to wait
on running checks, and abort if any check failed, I didn't want to
bundle that improvement into this PR - it's already big enough.

As a meaningful improvement, we should have a Dagger package that bumps
versions.  It would have been so much easier to use that Dagger package.
That implies us switching our GitHub Actions to Dagger, which we should
totally do. Small steps ftw!

Next step: run 0.1.0 release manually
Step 2: run 0.2.0-alpha.1 release manually
Step 3: wait for 0.2.0-alpha.2 to be produced automatically, tomorrow.

Usage:
$PROG bump (major|minor|patch|release|prerel [<prerel>]|build <build>) <version>
$PROG compare <version> <other_version>
$PROG diff <version> <other_version>
$PROG get (major|minor|patch|release|prerel|build) <version>
$PROG validate <version>
$PROG --help
$PROG --version
Arguments:
<version> A version must match the following regular expression:
\"${SEMVER_REGEX}\"
In English:
-- The version must match X.Y.Z[-PRERELEASE][+BUILD]
where X, Y and Z are non-negative integers.
-- PRERELEASE is a dot separated sequence of non-negative integers and/or
identifiers composed of alphanumeric characters and hyphens (with
at least one non-digit). Numeric identifiers must not have leading
zeros. A hyphen (\"-\") introduces this optional part.
-- BUILD is a dot separated sequence of identifiers composed of alphanumeric
characters and hyphens. A plus (\"+\") introduces this optional part.
<other_version> See <version> definition.
<prerel> A string as defined by PRERELEASE above. Or, it can be a PRERELEASE
prototype string (or empty) followed by a dot.
<build> A string as defined by BUILD above.
Options:
-v, --version Print the version of this tool.
-h, --help Print this help message.
Commands:
bump Bump by one of major, minor, patch; zeroing or removing
subsequent parts. \"bump prerel\" sets the PRERELEASE part and
removes any BUILD part. A trailing dot in the <prerel> argument
introduces an incrementing numeric field which is added or
bumped. If no <prerel> argument is provided, an incrementing numeric
field is introduced/bumped. \"bump build\" sets the BUILD part.
\"bump release\" removes any PRERELEASE or BUILD parts.
The bumped version is written to stdout.
compare Compare <version> with <other_version>, output to stdout the
following values: -1 if <other_version> is newer, 0 if equal, 1 if
older. The BUILD part is not used in comparisons.
diff Compare <version> with <other_version>, output to stdout the
difference between two versions by the release type (MAJOR, MINOR,
PATCH, PRERELEASE, BUILD).
get Extract given part of <version>, where part is one of major, minor,
patch, prerel, build, or release.
validate Validate if <version> follows the SEMVER pattern (see <version>
definition). Print 'valid' to stdout if the version is valid, otherwise
print 'invalid'.
