[BUG] rename doesn't consider custom MOUNT

[gahr]

[MANDATORY] Describe the bug [MANDATORY]
The rename command contains a update_fstab routine to update the fstab file of the jail to the new name. However, this is not applied to custom mounts, e.g., those initiated by a MOUNT command in a template.

[MANDATORY] Bastille and FreeBSD version (paste bastille -v && freebsd-version -kru output)
0.10.20231125
14.0-RELEASE-p3
14.0-RELEASE-p3
14.0-RELEASE-p4

[MANDATORY] How did you install bastille? (port/pkg/git)
pkg

[optional] Steps to reproduce?

1. create a jail named foo
2. apply a template that contains a MOUNT command, e.g., MOUNT /root/bastille/data data nullfs rw 0 0
3. rename the jail: bastille rename foo bar
4. see how the custom entry in the jail fstab file still points to the old path: /root/bastille/data /usr/local/bastille/jails/foo/root/data nullfs rw 0 0

[optional] Expected behavior
The rename command takes care of updating all entries in fstab, so my entry would be updated to /root/bastille/data /usr/local/bastille/jails/bar/root/data nullfs rw 0 0

This might be simplistic but works for me :)
