Add support for specifying a list of default IDEs to be displayed on
the Workspace page. This allows users to see multiple IDE options
simultaneously. Ensure no duplicates are included and validate
provided IDE codes against allowed set. Adjust logic to dynamically
render IDE buttons based on specified defaults, improving flexibility
in user interface setup.
Another try at #96. I cannot reproduce the error on deployment and dev.coder.com.
It also removes Community editions, `Rider`, and `DataGrip` as they are not supported for Remote Development.
From #66, also added testing for `jetbrains-gateway`.
## Regions
Azure and AWS were simple, but there is no error message when no region is selected:

Open to feedback on this.
## Jetbrains Gateway
The Jetbrains gateway default IDE satisfies a ton of logic in the template, so allowing `null` would lead to a lot of patchwork `try` statements. Now it's implemented to use the first IDE in the `jetbrains_ides` as the coder_parameter default for cleanliness.
Let me know your thoughts.
