Can't specify editorconfig for `--config-path`

$ stylua ./lua/lint/linters/fsharplint.lua --config-path ./.editorconfig

It is intentional that --config-path can only process stylua.toml files.

We could special case it to use editorconfig parsing instead if the filename passed is specifically .editorconfig
