Re-enable auto-merge for modifications

[politician]

Following @rmetzler's proof that relying on an unverified git committer (and author) is inherently not secure, I have disabled the auto-merge functionality for modifying records.

Some food for thoughts for re-enabling it:

• Inspect the PR info given to GitHub actions see if there's something useful there (eg. the github username?)
• Only accept modifications from signed commits
• ???

Enabling Branch Protection and enabling the Require signed commits rule could work.

Just found this today.

To enable:

Settings > Branches > Add branch protection rule

• Input branch name or a branch name pattern
• Check the Require signed commits rule
• Create

Signed commits could work so that the GH Actions program checks for either a modification of one line, OR a modification of many lines but all belonging to the same committer, but then this might increase confusion for people who use their email and their noreply@github email interchangeably. Such a change would probably take a couple months to a whole year, depending on the amount of activity present on this repository.
