chore: Upgrade strum (#7337)
## Summary
This PR upgrades `strum` from 0.24.x to 0.25.x.
The breaking changes are:
* strum macros now uses syn2
* The `to_string` behavior changed when using `default`. I did a quick search, we aren't using `strum(default)`
`strum` now has a `#[derive(EnumIs)]` macro that generates `is_` methods.
## Test Plan
cargo test
