fix!: options in .editorconfig not work with shfmt

Must pass --filename option to shfmt.
When shfmt read content from stdin, it doesn't know the filename and its extension.
So it won't match the patterns "[*.sh]" and "[*.bash]" in .editorconfig.

Do not pass any Parser and Printer options like -i/-p/-bn/-l. It will cause the .editorconfig not to be loaded.
See https://github.com/mvdan/sh/blob/23633a432f903599a4ce46c30c4337e413a26ef1/cmd/shfmt/main.go#L186-L196

Breaking Change:

Removed shfmtConfig options. Use the .editorconfig options instead of.
The .editorconfig options of shfmt refer to https://github.com/mvdan/sh/blob/master/cmd/shfmt/shfmt.1.scd#examples
