Update Mailspring to 1.7.2
Updated Mailspring to 1.7.2 which includes bug fixes for calendar and contact sync errors. Fixes T8576.
- You can now add Instagram handles to your email signatures.
- When switching layout modes, Mailspring clears the selection to avoid an immediate mark-as-read.
- Resolves some scenarios that caused calendar and contact sync to crash, unnecessarily stopping email sync.
Test Plan: Tested 1.7.2 by sending, recieving, and archiving emails from a Gmail account. Everything looked and functioned as expected.
