Why can perl not be found in custom rule

[andrewkatson]

I am working on openssl for Bazel on Windows and I run into a curious error. When a "normal" rule runs StrawberryPerl is on the PATH in my github action. But when the custom rule I wrote runs PATH is altered to exclude StrawberryPerl even though I set rules_perl as a needed toolchain.

I am curious why this is.

I see that rules_perl isn't ready to use on Windows but every github action Windows container already comes with Strawberry perl and bazel is overriding PATH to not include Stawberry perl when it comes to custom rules. This feels odd.
