Running the CLI inside of a Github action triggers an stdin warning

[janpieterz]

See the run here.

Run npx prettier --write .
Error: UndefinedParserError: No parser could be inferred for file "stdin".
Error: Process completed with exit code 1.

Looks like something is falsy around this detection of TTY on GitHub runners (we've ran into other odd issues with that but I am struggling to find a quick fix).

Looks like this pull request fixes running it - based off of this GitHub Actions thread.

I'm seeing this on my computer as of the last alpha version update.

Does anyone have a repro that I can try locally? 🤔 "npx prettier --write ." doesn't do it for me.

This commit should fix it in the next release.

@fabiospampinato happy to help test this fix. Is there a pre-release available on npm yet?

[fabiospampinato]

@mareksuscak not yet, but I've asked the maintainers to make a new release, it shouldn't take too long.

@mareksuscak alpha10 just got released

@mareksuscak could you check if this fixes the issue for you? Thanks.
