Ability to use/configure Format On Save to work with prettier configs within folders

[cwhitemaddox]

Right now, with the prettier-vscode extension installed, the extension will recognize prettier configs (e.g. .prettierrc) that are on the root of the vscode workspace/project, but it will not recognize configs that are within folders in that vscode workspace.

It would be helpful to have the prettier-vscode extension recognize and honor the prettier configs that are within folders in a vscode workspace. This is especially helpful in a monorepo context, where different folders of the monorepo can have different package.jsons and different prettier configs.

If, for examble, you have a folder structure in a workspace like so:

codebase-1/
  package.json
  .prettierrc
  src/
    first-script.ts
codebase-2/
  package.json
  .prettierrc
  src/
    second-script.ts

It is currently possible to cd into codebase-1/ and codebase-2/ and run, e.g. npx prettier --write src/, for each, but that does not happen automatically on save like the prettier-vscode extension so helpfully enables.

However, with the vscode workspace opened on code structure above, opening codebase-1/src/first-script.ts and saving the file (with Format On Save enabled), prettier-vscode will not use the config from codebase-1/.prettierrc.

To add to the issue, this also affects .prettierignore files. The current workaround is to duplicate the ignore file contents from subfolders into the repo root.

I can also verify this behaviour with .prettierignore files in my setup as reported in this StackOverflow post. Reading the documentation I expected to be able to create a .prettierignore file in my project but it was being ignored and like the other reports it has to be in the workspace root which in a multiroot workspace is the parent of all projects.

After some further tests it seems .prettierrc.json is recognised in any directory and does not have to be in the root directory of the project, however .prettierignore still has to be in the root directory to work at all. The workaround I've found is to create a prettierrc.json in any folder I want to ignore with a single { "requirePragma": true } rule inside.
