Add Bandit Support

[Rio517]

There may be an issue with live_admin when switching to bandit. I get this when loading any live_admin page:

[error] GenServer #PID<0.1178.0> terminating

I'm using live_admin 10.2 modified to support live_view 0.20.x.

Here is the description of the issue: https://github.com/mtrudel/bandit/issues/141

And proposed solution: https://github.com/mtrudel/bandit/issues/141#issuecomment-1537872411

Hope that is helpful.

Should be fixed in latest main.

This is resolved for me.
