Add Signoff Input

[xanjohns]

It would be great if there were an input to the action that would add the "Signed-off by" line (--signoff) when making commits.

[BetaHuhn]

This should already be possible with the COMMIT_BODY input. It gets appended to each commit message (separated by two line returns).

In your case it would be:

- name: Run GitHub File Sync
  uses: BetaHuhn/repo-file-sync-action@v1
  with:
    GH_PAT: ${{ secrets.GH_PAT }}
    COMMIT_BODY: "Signed-off-by: Username"

The commit message will look like:

🔄 Synced local '<filename>' with remote '<filename>'

Signed-off-by: Username
