re-select "set as workspace env" does nothing

Testing #24503

1. select venv as the workspace venv already
2. click "set as workspace env"
3. 🐛 nothing seems to happen because I am selecting the environment that was already selected
   ideas:

• grey out that option
• show notif that it was already selected

@cwebster-99 @luabud I need some input here. The issue here is that we want to show the ✔️ to select for multi-project scenarios. Suppose you have two environments, and two projects, and each one is selected for each project. Then the ✔️ is necessary as you might want to select the same environment for both projects. E.g, env1 -> project1, env2-> project2, user might want to select env1 -> project1, project2. By removing ✔️it makes it harder to select it.

But I also see the confusion that people can have with clicking the ✔️ on the selected environment.

Discussed offline and decided to surface a notification communicating that the environment has already been selected in the following scenario

• User has one folder/project open
• User tries to select the same environment that is already selected
