endOfLine changed from auto to LF in v2.0.0 doesn't take effect

Summary

Line endings was changed from auto to LF in prettier v2.0.0. However this doesn’t change CRLF files to LF when formatting.

Github Repository to Reproduce Issue

Any CRLF file prettier supports will do

Steps To Reproduce:

Use prettier v2 default config

1. Open a CRLF file (ie .ts) that is otherwise correctly formatted
2. Observe that vscode doesn’t report line ending errors
3. Open command pallet and run “Format document with…” select “prettier”
4. Observe that line endings are still CRLF and prettier still doesn’t report errors

Expected result

Prettier should report line ending errors. Prettier should change line endings to LF on format.

Actual result

Line endings are still CRLF after formatting.

[vasilii-kovalev]

It seems that even "endOfLine": "lf" doesn’t work in VS Code automatically (without running Prettier via CLI).

add .editorconfig file can work
