Only generate new header ids when the content changes

[cewert]

Is your feature request related to a problem? Please describe.

I'm using jsdoc and this github action https://github.com/stefanzweifel/git-auto-commit-action to automatically update the doc files after a PR is merged.

My problem is that because this theme generates new header ids for each file regardless if there has been changes, that means that in order for me to make this workflow work, we would need to update every single doc .html file because of the new ids instead of just the files with changes.

Describe the solution you'd like

Only modify the .html files if there have been changes

Describe alternatives you've considered

Add some kind of config setting to allow users to opt out/in to this behavior

Additional context

These are the ids I'm talking about:
