`JuliaFormatter.format` has a different behaviour than `Format Document` in VS Code

[alex180500]

Input file

1+2:3

Given this input it remains completely unchanged from VS Code Format Document without any .JuliaFormatter.toml (which should then default into the MinimalStyle).

But the JuliaFormatter.format on the same input (and same for format_text or format_file), gives instead (1+2):3.

I cannot also see any way to change such behaviour from the .toml file, seems like it is a parser problem of the vscode extension (maybe not updated JuliaFormatter version?).

Two possible explanations: 1) I think JuliaFormatter.format etc don't use MinimalStyle but DefaultStyle by default. We had a plan to streamline all of this (domluna/JuliaFormatter.jl#559) but I think that never moved forward on the JuliaFormatter.jl side of things, 2) We still use JuliaFormatter.jl v1 in the language server. I tried to migrate in the fall, but had to revert because v2 had too many bugs. Not sure what the current situation is and whether we can try again.
