Allow more characters in Golang bench outputs

[vaeryn-uk]

This adds , and = as acceptable characters as Go benchmark names. Previously benchmarks with these character were not detected by this action.

I've run across this problem specifically using table benchmarks, where there are multiple changing variables per benchmark. foo=bar,baz=qux feels like a natural name for these, e.g.

BenchmarkWorldTick/agentCount=1,interactableCount=1,stationary=0,awarenessRange_2000-16                    69483             16465 ns/op
BenchmarkWorldTick/agentCount=20,interactableCount=10,stationary=50,awarenessRange_2000-16                   589           2140095 ns/op
BenchmarkWorldTick/agentCount=200,interactableCount=100,stationary=100,awarenessRange_60-16                  194           5987727 ns/op
BenchmarkWorldTick/agentCount=200,interactableCount=100,stationary=100,awarenessRange_120-16                 174           6981772 ns/op
BenchmarkWorldTick/agentCount=200,interactableCount=100,stationary=100,awarenessRange_240-16                 100          10206439 ns/op
BenchmarkWorldTick/agentCount=1000,interactableCount=100,stationary=100,awarenessRange_30-16                  24          47655071 ns/op
