The generated GitHub GraphQL flow types are a kind of snapshot, and it
can be hard to remember/discover how to update them when making changes
to schema. Therefore, I've included them in the snapshot update script.
Test plan: I used it to update the types, and it worked as intended.
As SourceCred has evolved, we've grown more and more snapshot tests that
are not included in Jest. The GitHub plugin has two ad-hoc snapshot
tests, the Git plugin has one, and the sharness test suites have one.
This makes it difficult to keep track of where to update snapshots when
core changes are made. To fix this, I've added a script,
`scripts/update_snapshots.sh`, which updates snapshot tests across the
project.
Test plan: I removed existing snapshots across the codebase, ran the
snapshot tester, and they correctly regenerated.
