Build speed: components/supervisor:docker and glitpod-cli

[mads-hartmann]

Description

This uses the Leeway package version when populating versions.txt - the motivation for this change is to improve build speed. When we use argdeps the package build cache will be invalidated whenever the argument changes. So having an argdeps on version means that we'll rebuild components/gitpod-cli:version and components/gitpod-cli:app on every CI build. Because components/supervisor:docker depends on components/gitpod-cli:app it means we'll rebuild that every time too.

This will reduce our build speeds by 38s (based on the example shown below).

Discussion: I went with using the Leeway package version. We could also use the git commit (__git_commit) or even use version but then just know it will only be bumped when the package is actually modified. We could also include all three.
⬆️ Update: We decided on using the git commit instead here.

How to test

With the changes in this PR I triggered two commits to show that it no longer rebuilds components that didn't change. The arrows in the before images indicate what we'll no longer be rebuilding every time.
