Change:
- Variables used in ``when`` conditionals are no longer parsed and
attempted to be converted to booleans. All non-empty strings are
considered true (empty strings, false).
Test Plan:
- Updated existing tests
- Added a bunch of new tests with various kinds of truthy/falsy
values.
Tickets:
- Fixes#74134
