JsPrettier does not properly configure parser for Less files

Reopening #199.

When reporting an issue, please include the following information in your post:

• Explain the Issue and Expected Behavior
• Prettier version
• JsPrettier Plug-in Version
• Platform Details

Explain the Issue and Expected Behavior

When prettying a Less file, it forces the parser to use CSS, which prevents Prettier from parsing and prettying the content properly. It should use SCSS instead.

Prettier version

1.19.1

JsPrettier Plug-in Version

1.28.5

Platform Details

- Sublime Text Version: 3.2.2
- Sublime Text Build: 3211
- Operating System Name: macOS
- Operating System Version: 10.15

Generated Prettier command line arguments

-----------------------------------------
 JsPrettier DEBUG - Prettier CLI Command
-----------------------------------------

/Users/percyhanna/.config/yarn/global/node_modules/.bin/prettier \
  --stdin \
  --config /path/to/.prettierrc \
  --config-precedence cli-override \
  --parser css \
  --use-tabs false \
  --ignore-path /path/to/.prettierignore \
  --stdin-filepath /path/to/file.less \
  --loglevel debug \
  --cursor-offset 6930

Prettier reported the following output:

[debug] normalized argv: {"_":[],"color":true,"editorconfig":true,"stdin":true,"use-tabs":false,"config":"/path/to/.prettierrc","config-precedence":"cli-override","parser":"css","ignore-path":"/path/to/.prettierignore","stdin-filepath":"/path/to/app/assets/stylesheets/landing_pages.less","loglevel":"debug","cursor-offset":6217,"plugin-search-dir":[],"plugin":[],"debug-repeat":0}
[debug] load config file from '/path/to/.prettierrc'
[debug] loaded options `{"jsxSingleQuote":true,"singleQuote":true,"trailingComma":"es5"}`
[debug] applied config-precedence (cli-override): {"filepath":"/path/to/app/assets/stylesheets/landing_pages.less","cursorOffset":6217,"jsxSingleQuote":true,"parser":"css","singleQuote":true,"trailingComma":"es5","useTabs":false}

Is the same behavior observed when run against Prettier directly?

If I remove --parser css then it works as expected. Or, if I use --parser scss.

The contents of your User/JsPrettier.sublime-settings file

{
  "debug": true,
  "auto_format_on_save": true,
  "prettier_cli_path": "/Users/percyhanna/.config/yarn/global/node_modules/.bin/prettier"
}

The contents of your <project_name>.sublime-project file (if applicable)

n/a

Steps to reproduce the behavior

This issue is specifically related to this bug that has been fixed in prettier: https://github.com/prettier/prettier/pull/2034

If I save a .less file with the &:extend content, then it adds the space, thus breaking the syntax in less.

div {
  &:extend(.something);
}

@jonlabelle I suppose it would be something like this: #209
