Bump async-lock from 2.7.0 to 2.8.0

[dependabot]

Bumps async-lock from 2.7.0 to 2.8.0.

Release notes

Sourced from async-lock's releases.

v2.8.0

• Fix a bug where the SemaphoreGuard::acquire_arc future would busy wait under certain conditions (#42).
• Add a Semaphore::add_permits() function to increase the number of available permits on the semaphore (#44).
• Make RwLockReadGuard covariant over its lifetime (#45)
• Add RwLockReadGuardArc, RwLockWriteGuardArc, and other reference counted guards for the RwLock type (#47).
• Loosen the Send/Sync bounds on certain future types (#48).
• Fix UB caused by the MutexGuardArc::source function allowing the user to drop an object in a different thread than the one it was acquired in (#50). This is a breaking change, but in the name of soundness. Therefore it doesn't break any valid behavior.
• Fix a bug where this crate would not compile properly on wasm64 (#51).
