Add more doc for ERB-Lint

[kennyadsl]

👋 Hey there,

This PR completes @aldesantis and @gylaz work done into #1641 to allow linting ERB files by adding some documentation around this new addition.

Since I have no access to the houndci/linters repo, in the PR I assumed that:

• ERB linting is done with this tool
• linter code is located into lib/linters/erb_lint
• default config is located into config/erb.yml

Let me know if I should change something.

Also, I think you should add an ERB help page (similar to this one) and update the supported-linters page as well. Let me know if I can be of help here.

Thanks @kennyadsl. 🙌 I added you to linters.

Also, I think you should add an ERB help page (similar to this one) and update the supported-linters page as well. Let me know if I can be of help here.

If you write it up I'll copy/past right into a new Intercom page, that would be great.

ERB

Review ERB with Hound

Hound uses erb-lint (0.0.28).

Please notice that this linter is disable by default. To enable ERB style
checking, add the following to your .hound.yml

erblint:
  enabled: false

By default, erb-lint default configuration is used. You can change the
way erb-lint is configured by simply creating a proper config file into
your project and reference it in your .hound.yml

erblint:
  enabled: true
  config_file: .erb-lint.yml

Note: this is changed from having erb keys to erblint due to an internal hound change that now needs linters names instead of languages (see comments below).

Thanks again @kennyadsl!

@salbertson after reading this @gylaz comment I think we should change the erb key into the houndci.yml file to erb_lint

[kennyadsl]

Ah just noticed that it's already done! We are all good!

[kennyadsl]

@salbertson @gylaz I think this is ready to merge, or you do have other comments?

[kennyadsl]

ping @salbertson @gylaz 🙂
