Offer a way to update php.ini at startup based on `FILE_UPLOAD_SIZE_LIMIT`

[stavros-k]

Changing the FILE_UPLOAD_SIZE_LIMIT while bookstack does not error out, php.ini dictates the max file is 10M hardcoded.

Alternatives:

Display a log message when FILE_UPLOAD_SIZE_LIMIT is changed informing user that has to bind mount a modified php.ini file

Thanks

Take a look at the linked PR. I'll happily review a PR to make changes to php.ini if you bring one forward.
