perf(linter): use `aho-corasick` instead of `regex` for string matching in `jsx-a11y/img-redundant-alt` #17680

Workflow file for this run

.github/workflows/benchmark.yml at 608d637

	# Benchmarks are sharded.
	#
	# Each benchmark (parser, transformer, etc) runs in parallel in a separate job.
	# Linter benchmarks are much slower to build and run than the rest, so linter benchmark
	# is built in 1 job, and then run on each fixture in parallel in separate jobs.
	# When all jobs are complete, a final job uploads all the results to CodSpeed.
	#
	# Sharding is not natively supported by CodSpeed, so we use a hacky method to achieve it.
	# 1. Intercept the data which `CodSpeedHQ/action` would normally upload to CodSpeed for each job.
	# 2. Once all runs are complete, combine the data for all the runs together.
	# 3. Upload the combined data to CodSpeed as one.
	# This is performed by some short NodeJS scripts in `tasks/benchmark/codspeed`.
