feat: add ts-standard

[pyrho]

Thanks for the plugin !

Cheers.

edit: actually it's not working yet 😬 , converting to draft until I figure it out.

There's currently an issue with standard which prevents feeding files from stdin, see standard/ts-standard#273 .
Discarding this for now. Sorry for the noise.

@pyrho did you try stdin = false? Conform supports formatters that don't accept stdin by writing a temp file and formatting it in-place.

Hey, just tried that but then there's another issue; it seems like ts-standard ignore hidden files by default.

File ignored by default.  Use a negated ignore pattern (like "--ignore-pattern '!<relative/path/to/filename>'") to override

I've tried all the combinations I could think of for the ignore pattern but I can't make it work, this message actually comes from eslint (which is used by ts-standard) so my gut tells me that ts-standard does not propagate the command line option all the way to eslint.

ts-standard feels a bit rough around the edges right now, might be worth revisiting in a year or two :)

In any case, thank you for conform!
