Support hard_tabs Zed setting.

With this extension installed, my hard_tabs setting is ignored and my justfile's indentation is forcibly converted to spaces no matter what I do. Only uninstalling the extension allows me to save the file with hard tabs.

Which is extra funny since the author is jackTabsCode.

@AmyGilhespy a workarround is to ctrl+k s, that skips the formatter.

Without the hard_tabs setting, I would also expect it to not convert formatting and just stick with what is detected in the file already.

@GeertJohan That's really funny. Thanks a bunch for the workaround! It's very helpful until this gets solved.

It seems the formatting as provided by just-lsp defers to just --fmt --unstable, which discards detected indentation. I'm working on a PR over at the just repo which should at least make it such that pre-existing indentation is kept in place.
