Hold Preview Hosting more than 30 days

### The use case you're trying to solve

We like that everything is automatic, and uses github actions. However, we want to hold the preview longer than 30 days. Sort of like long running history.

### Change to the action that would solve that use case

Allow for expiration to be longer then 30 days.

### Other considerations

Question: Has anyone asked for longer expiration time? What were their solutions?

Start by locating the action's handling of Firebase Hosting preview expiration and reviewing how the 30-day limit is configured. The change is complete when users can request or receive an expiration longer than 30 days while existing preview deployment behavior remains intact; the issue names no files or tests to run.
