fix: Update language names to better represent embedded templates

[marcoroth]

This pull request updates the language names for .html.erb and .yml.erb files.

The previous names HTML/ERB and YAML/ERB used a forward slash which semantically suggests "either/or" rather than the actual relationship where ERB is embedded within HTML or YAML.

Using HTML+ERB and YAML+ERB with a plus sign better conveys that these are composite languages.

I like that change! However, before releasing a new version with this update, we need to complete some prerequisites. Otherwise, some features like Tailwind autocomplete will be broken:

• Update the Emmet extension
• Add HTML+ERB and YAML+ERB to the Tailwind list of supported languages (here)
• Wait for the new release of the Emmet extension
• Wait for the new release of Zed
• Merge this PR
• Release the new version of the extension

Thanks for the feedback! I see the issue and wasn't aware what this is going to affect.

Kinda makes me wonder if the "Display Name" shouldn't be different from the "Language ID" itself.

Add HTML+ERB and YAML+ERB to the Tailwind list of supported languages (here)

We probably don't need Tailwind support in YAML+ERB files.

No worries, we still can land this PR. I will take care of updating Zed related parts.

I created an issue to track all prerequisites.
