Update ALLOWED_SSR_REGIONS constant for web frameworks

[jamesxabregas]

Description

Update list of ALLOWED_SSR_REGIONS in web frameworks config to include the current list of regions that support gen 2 Cloud Functions.

#5504 added the ability to select an SSR region other than 'us-central1', but it was limited to regions that supported Gen 2 Cloud Functions at the time which has since expanded. This change updates the list of supported regions.

Scenarios Tested

Tested deploying to new regions using config in firebase.json

frameworksBackend": {
      "region": "australia-southeast1"
}

Sample Commands

Commands have not changed.

As per previous functionality, run:

firebase experiments:enable webframeworks
firebase init hosrting
firebase deploy

Just wondering if there is any particular reason this hasn't been reviewed yet? I filled in the Google CLA and re-scanned. Are there some additional steps I need to take?

Sorry for the delay. LGTM

Hi maintainers, just wondering if there is something in particular I need to do to get this change merged?
It was approved 3 weeks ago but still waiting to be merged.

@alexastrum My project is starting to generate some fees related to intercontinental network egress.

V2 functions are already supported in a lot of regions.

Could we get this merged?

[jamesxabregas]

@alexastrum could you please merge these changes, or tell me what needs to be done to progress this. Thank you.
