Usage of exclamation mark (!) in Custom Links not possible

[Azmodeszer]

Deployment Type

Self-hosted

NetBox Version

3.6.6

Python Version

3.11

Steps to Reproduce

1. Set up a Custom Link.
2. Put https://<IP>/screens/dashboard.html#!/APView/{{ object.interfaces.filter(mac_address__isnull=False).first().mac_address }} as the Link URL.

Similar to #13011. Also see #14553.

Expected Behavior

The URL should be rendered with the ! intact.

Observed Behavior

The ! is encoded as %21, resulting in a broken link.

The exclamation mark probably needs to be added to the list of characters excluded from escaping when calling urllib.parse.quote().
