Bump AsyncFixer from 1.6.0 to 2.1.0

[dependabot]

Updated AsyncFixer from 1.6.0 to 2.1.0.

Release notes

Sourced from AsyncFixer's releases.

2.1.0

• AsyncFixer01: Add support for analyzing and fixing async local functions.
• AsyncFixer01: Detect unnecessary async in methods with terminal awaits in all if-else branches.
• AsyncFixer04: Detect fire-and-forget async calls in using var declarations (C# 8.0+) and warn when a task is returned from a using scope without being awaited. The disposable resource will be disposed before the returned task completes. (#​13)
• AsyncFixer04: Fix false positive when task is assigned to a variable and awaited later within the same using block (e.g., await Task.WhenAny(task, ...)).
• AsyncFixer06: Fix false positive for Assert.ThrowsAsync and similar assertion methods where discarding the Task<T> result is intentional.
• AsyncFixer03: Add test coverage for event handlers using Action<T> delegates. (#​16)
• Improve diagnostic messages and README for better AI assistant compatibility.
• AsyncFixer06: New analyzer to detect implicit Task<T> to Task conversion in non-async lambdas. Unlike async lambdas which produce compiler error CS8031, non-async lambdas silently discard the result. (#​26)
• AsyncFixer01: Fix false positive with await foreach statements. (#​41)
• AsyncFixer01: Fix false positives for ValueTask<T> return types.
• AsyncFixer02: Fix false positive with nameof(Task.Result). (#​30)
• AsyncFixer02: Fix false positive after Task.WhenAll - accessing .Result on awaited WhenAll tasks is safe.
• AsyncFixer02: Fix false positives in synchronous local functions and lambdas inside async methods.
• AsyncFixer03: Fix false positive with generic EventArgs types. (#​39)
• AsyncFixer05: Fix false positive with TaskTupleAwaiter and similar custom awaiters. (#​31)
• AsyncFixer05: Detect nested Task in return statements. (#​27)
• Code Fix: Correct nested invocation handling in Fix All operations. (#​37)
• Code Fix: Add parentheses when async conversion is followed by member access. (#​38)
• Upgrade Microsoft.CodeAnalysis to v4.8.0.

Looks like AsyncFixer is no longer a dependency, so this is no longer needed.
