Allow <s> tag and class attribute on <code> in comments (#7682) 

#### What type of PR is this?

/area code
/milestone 2.21.x
/kind improvement

#### What this PR does / why we need it:

Comments are allowed to contain `s` tags and `code` tags with class attributes for the following reasons:

1. `s`: The comment component uses tiptap editor's [strikethrough extension](https://tiptap.dev/docs/editor/extensions/marks/strike#:~:text=while%20you%20type.-,Restrictions,-The%20extension%20will) which enforces the use of `s` tags for strikethrough text and cannot be changed.
2. `code[class]`: Used for code highlighting (class="language-*")

#### Does this PR introduce a user-facing change?
