Enable checking .renovaterc.json5 files with pre-commit hook

[tpansino]

Adjust pre-commit hook file regex to allow for .json5 extensions, as these are valid for .renovaterc config files.

.renovaterc also needs to be supported as a filename, which is why CI is failing on the modified regex.

I suggest splitting .renovaterc and .renovaterc.(json|json5) into separate lines in the pattern. That also removes any need for the ?, since .renovaterc. is not a valid pattern.

Thanks for the contribution!

My apologies, I should have caught that.

I made a minor change to reflect the new regex in the catalog (which is used to generate the hook config), and this is good to go. I'll make sure to add credit in the changelog for you as well. Thanks again!
