ci(github): refactor ActionLint job to use the official installer

[petermetz]

1. Previously we just winged it with a bash script downloading another
   bash script to unzip the actionlint binaries.
2. From now on we'll use the GitHub action from the marketplace which
   has a lot of configuration options exposed in a convenient way such as
   what type of warnings to ignore, what version of actionlint to install,
   etc.

• Rebased onto upstream/main branch and squashed into single commit to help maintainers review it more efficient and to avoid spaghetti git commit graphs that obfuscate which commit did exactly what change, when and, why.
• Have git sign off at the end of commit message to avoid being marked red. You can add -s flag when using git commit command. You may refer to this link for more information.
