add a "shell" option

[Neo-Desktop]

Hi there,

I'd like to use the cmake-action script but have it run in a "custom shell"
(i.e. having it run in an alpine chroot provided by jirutka/setup-alpine@v1)

specifying a shell option on a run build step allows us to use the chroot

is it possible to add that same functionality to the cmake action?

Sure thing! I'll work on adding that feature for you right away. You can expect it to be included in the upcoming v1.3.0 release. Stay tuned!

All set, @Neo-Desktop!

Just hang tight until the next release on #55. Meanwhile, you can make use of the new feature in this action by specifying a specific tag (e.g., threeal/cmake-action@7ef2eb8).
