It's nice to have all extensions so we can easily copy paste :)

Re-use the instructions for setting the File Watcher program path in WebStorm when prettier is installed locally.

This fixes #3432, I think.

* Fix printing union types inside a function param type

* fix alignment

* docs(ignore): mention ignore file in Ignoring Code

While working on #3321, I needed to ignore an entire file, but the "Ignoring Code" section of the docs only describes how to ignore blocks of code, so I wasn't aware of the default ignore file.

(The `.prettierignore` file is mentioned in the CLI section, but easily overlooked there.)

This commit extends the introduction sentence of the "Ignoring Code" section and adds a new subsection to explain how to ignore files.

#3321 (comment)

* docs(cli): fix nesting error in heading hierarchy

The `--ignore-path` option currently appears as a third-level subsection of `--find-config-path` and `--config`, but this looks like an error.

This commit promotes the `--ignore-path` heading to the same (H2) level as the other CLI options.
