Fix regex pattern used to verify Cloud Storage bucket name

[aalej]

Description

Fixes #8152

From what I can gather, there are currently 2 formats being used for Cloud Storage bucket names. PROJECT_ID.firebasestorage.app for the new ones, PROJECT_ID.appspot.com for the old ones

Logging the bucketResourceNameTokens of new and old projects:
New:

--- bucketResourceNameTokens
[
  'projects',
  'PROJECT_ID',
  'buckets',
  'PROJECT_ID.firebasestorage.app'
]

Old:

--- bucketResourceNameTokens
[
  'projects',
  'PROJECT_ID',
  'buckets',
  'PROJECT_ID.appspot.com'
]

Scenarios Tested

Using an old project with that has a PROJECT_ID.appspot.com Cloud Storage bucket name:

1. Run firebase init extensions --project PROJECT_ID
2. Run firebase ext:install firebase/delete-user-data --project=PROJECT_ID
   • Answer all prompts
   • In extensions/delete-user-data.env

...
CLOUD_STORAGE_BUCKET=PROJECT_ID.appspot.com
...

3. Run firebase deploy

=== Deploying to 'PROJECT_ID'...
