Can this action be cached / sped up?

I am not as proficient with Github Actions, so forgive me for asking if this is a trivial thing.

For my project, I use this awesome action and it works as expected (Installs MinGW32 bit version). However, it takes 8-9 minutes to install MinGW. I was wondering if this step could be cached, as this step is everytime the same?
