Merge branch 'zj-env-external-url' into 'master'

Add an URL field to Enviroments

## What does this MR do?

Adds a field to the `enviroments` table to expose later in other features. Now I see the task list below, I noticed I forgot some minor things, but Ill adress those after the first review. 

## Are there points in the code the reviewer needs to double check?

The field is a string on the database, thus limited to 255 chars, which seems more than enough.

## What are the relevant issue numbers?

Closes #19527

## Screenshots (if relevant)
