Hide publish button for users with no tagmanager_use_custom_templates capability

[9joshua]

A customer reported that when they publish a container with only MTM Write capability the resulting version is empty with all Tags, Triggers and Variables deleted.

I tested this on my own instance by doing the following:

1. Create a User with Write permission to the Site ID - This will provide Tag Manager Write capability.
2. Edit a Trigger in the container
3. Publish a new versions
4. Inspect the versions history and export the JSON file for the version...

{"idcontainer":"jgh7DXLd","idsite":5,"context":"web","name":"Default Container","description":"This container was auto generated when the website was created.","ignoreGtmDataLayer":0,"created_date":"2023-03-03 03:11:16","updated_date":"2024-04-11 21:02:51","created_date_pretty":"Mar 3, 2023 16:11:16","updated_date_pretty":"Apr 12, 2024 09:02:51","revision":129,"version":{"name":"225","description":"","revision":129,"created_date":"2024-04-30 03:32:23","created_date_pretty":"Apr 30, 2024 15:32:23","updated_date":"2024-04-30 03:32:23","updated_date_pretty":"Apr 30, 2024 15:32:23"},"tags":[],"triggers":[],"variables":[]}

It's worth noting that this issue did not occur when the same User was given "Use Custom Templates" MTM capability.

@9joshua I have found the problem, along with write permission, tagmanager_use_custom_templates capability is required

We should ideally hide the publish button if that capability is not present.
