chore(deps): upgrade dependencies for this repo only (#335)

This PR upgrades dependencies used by this repo
(`cdktf-repository-manager`) to their latest version based on the
version range specified in the `package.json` file.
For reference, here is the output from `yarn outdated` prior to running
`yarn upgrade` which was used to produce this PR:

Note that this auto-update process only stays within specified version
ranges (typically minor or patch). If you want to upgrade to newer
versions beyond those, you will need to manually check out this
repository and run the command `yarn upgrade [package] --latest`.

For future reference: the reason why we're not using Dependabot for this
is because this repo has a tendency to run into rate limits, and
Dependabot produces so many PRs and workflow runs that it'd be likely to
hit those limits quickly.
