feat(scripts/autolabel): use Cli and integrate curl call into autolabel

[joneugster]

• use Cli for lake exe autolabel
• add arguments --pr xxx --gh and --pr xxx --curl <TOKEN> to chose between different interaction methods with github
• add --force to skip the check whether labels are already present. (note: the current curl setup doesn't perform this step, so I left it as a TODO in this PR, too)
• make CI-workflow simpler and more robust by removing current stdout-parsing of the debug-messages which autolabel emits.

Testing

Make some local changes and commit them. Ensure your local origin/master is in sync with upstream/master if you are on a fork.

• lake exe autolabel: prints the labels which would be applicable
• lake exe autolabel --pr 34952 --gh --force adds these labels to this PR using gh.
• lake exe autolabel --pr 34952 --gh adds these labels to this PR using gh if no topic labels are present.
• lake exe autolabel --pr 34952 --curl <ACCESS_TOKEN> adds these labels to this PR using curl. This requires a github access token for authentication
