ruby: Capture the heredoc content only and downcase the language (#12532)

# Summary

Hi. Current `heredoc` injection for Ruby language captures the
`heredoc_end` token. That's a bit incorrect because we want to capture
the content only. Suppose we have the following Ruby code:

```ruby
<<~JS
  function myFunc() {
    const myConstant = [];
  }

  let a = '1'
JS
```

And this is its syntax tree:

```
[program] [0, 0] - [7, 0]
  [heredoc_beginning] [0, 0] - [0, 5]
  [heredoc_body] [0, 5] - [6, 2]
    [heredoc_content] [0, 5] - [6, 0]
    [heredoc_end] [6, 0] - [6, 2]
```

Current injection capture all content of the `heredoc_body`:

But we want to capture the `heredoc_content` only and this PR resolves
that, additionally it downcases the language like Zed does in other
languages like Terraform.
