Property names/keys with more than 80 symbols get prefixed with question mark ?, and colon : gets wrapped onto the next line

[MurzNN]

Describe the bug

I have a YAML file like this:

services:
  Drupal\some\long\service\name\name\name\name\name\name\name\name\na\length_80:
    tags:
      - name: event_subscriber

  Drupal\some\long\service\name\name\name\name\name\name\name\name\nam\length_81:
    tags:
      - name: event_subscriber

And the formatter always changes it to the:

services:
  Drupal\some\long\service\name\name\name\name\name\name\name\name\na\length_80:
    tags:
      - name: event_subscriber

  ? Drupal\some\long\service\name\name\name\name\name\name\name\name\nam\length_81
  : tags:
      - name: event_subscriber

So, names/keys with a length of more than 80 symbols get prefixed with the question mark ?, and the colon : gets wrapped onto the next line.

Expected Behavior

The formatter should keep the original formatting.

Current Behavior

See above.

Steps to Reproduce

1. Create a YAML file with the content in the first code block.
2. Format the file.
3. See the wrong changes.

Seems the source of this issue comes from this Prettier issue https://github.com/prettier/prettier/issues/5599 and seems we should just bump the Prettier version to a fresher one?

It may sound obvious, but may help someone experiencing the same issue.

A simple workaround for this is changing Print Width formatter settings to some higher value (e.g. 999).

This was driving me nuts - I had to edit with "Language Mode : Yaml" but modify to "Language Mode: [anything else..]" before saving. Workaround from @nickshoe worked like a charm.
