Enable HAML-LINT linters

What does this MR do?

This MR enables new HAML Linters as mentioned in #22072 (closed) (particularly in this comment)

• AltText
• ClassAttributeWithStaticValue
• FinalNewline
• HtmlAttributes
• ImplicitDiv
• SpaceBeforeScript
• TrailingWhitespace
• SpaceInsideHashAttributes

Are there points in the code the reviewer needs to double check?

Pretty much every change needs to be reviewed as we want to be sure that an attempt to fix a Lint rule doesn't cause any unintended side-effect (which otherwise doesn't happen)

Why was this MR needed?

See #22072 (closed) and discussion thread in same issue.
