Increase Content field size of gpg_key and public_key to MEDIUMTEXT (#…

…20896) (#20911)

Backport #20896

Unfortunately some keys are too big to fix within the 65535 limit of TEXT on MySQL
this causes issues with these large keys.

Therefore increase these fields to MEDIUMTEXT.

Unfortunately the migration in #20896 cannot be backported to 1.17 so
affected users will have to use `gitea doctor recreate-table gpg_key public_key`

Fix #20894
