textproc/ruby-haml: update to 6.0.6

6.0.0 (2022-09-21)

* Replace the implementation with Hamlit

  - Haml 6 is about 1.7x faster than Haml 5 in this benchmark.
  - The parser is kept as is, but everything else is replaced.
  - The haml CLI interface was also replaced.
  - The interface of Haml::Engine is changed. Haml::Template is most likely
    what you need now.
  - Most Haml helpers are removed.

    Rails:

Kept: find_and_reserve, preserve, surround, precede, succeed,
      capture_haml

Removed: block_is_haml?, flatten, haml_concat, haml_indent,
haml_tag, haml_tag_if, html_attrs, html_escape,
init_haml_helpers, is_haml?, list_of, non_haml, tab_down,
tab_up, with_tabs

    Tilt:

Kept: preserve

Removed: block_is_haml?, capture_haml, escape_once,
find_and_preserve, flatten, haml_concat, haml_indent,
haml_tag, haml_tag_if, html_attrs, html_escape,
