[5.x]: Matrix field block configuration buttons not disabled when admin changes disallowed

[mike-moreau]

What happened?

Description

I have a site in staging with admin changes not allowed. I can view and click the buttons to modify available blocks on a matrix field. Although the buttons do not work (server error) I think it would be best if they were not clickable.

Steps to reproduce

1. disallow admin changes
2. view a matrix field

Expected behavior

Buttons disabled

Actual behavior

Buttons enabled
