Add shared credentials for Bandhan Bank (bandhanbank.com → bandhan.bank.in)

[mangeshraut712]

Summary

Bandhan Bank moved its public site from bandhanbank.com to bandhan.bank.in. This adds a from/to shared-credentials group so passwords saved for bandhanbank.com autofill on bandhan.bank.in.

fromDomainsAreObsoleted is true because the old host no longer serves the site; it 302s to the new one.

This PR is Bandhan only.
