Convert Threat Monitoring environment picker to GlDropdown

See merge request gitlab-org/gitlab!54309

This reverts https://gitlab.com/gitlab-org/gitlab/-/merge_requests/53326
since the endpoint created from the pre-signed URL is incorrect. For S3
virtual hostnames (e.g. `https://bucket.us-west-1.amazonaws.com`, the
bucket name should be ignored, so the endpoint should be
`https://us-west-1.amazonaws.com` in this case. This causes the wrong
endpoint to be used (`https://bucket.bucket.us-west-1.amazonaws.com`).

A workaround for AWS S3 users is to pass `endpoint: s3.amazonaws.com` as
a config.
