"language_version" values in examples are not quoted as explicit yaml strings

[gyermolenko]

Site gives examples like "language_version: 2.1.5" e.g. here

cfgv checker expects string.

So if language_version starts with digit like

repos:
  - repo: https://
    rev: beef
    hooks:
      - id: some-id
        language_version: 3.7

it causes errors like this

An error has occurred: InvalidConfigError: 
...
==> At key: hooks
==> At Hook(id='some-id')
==> At key: language_version
=====> Expected string got float

2.1.5 is not a float

as with yaml, if it could be a float and you want a string you'll need to quote it
