Add guardrail to `self-signed-certificates` and `manual-tls-certificates`

Could someone please add a new guardrail to self-signed-certificates that allows integer tracks (1, 2, 3… aka \d+)?

edit: May as well do the same for Manual TLS Certificates as it will require the same tracks

Cheers,

Hi,

The \d+ track has been created for both charms.

Thanks,

Odysseus

Thanks @odysseus-k !
