Reviewer's Guide by Sourcery

This pull request addresses two issues in the HTML replacer functionality: handling of elements without attributes and filtering out carriage return characters in attribute names. The changes are implemented in the createHTMLReplacer function within the src/replacer/html.ts file.

File-Level Changes

Files	Changes
src/replacer/html.ts	Added a null check using the optional chaining operator (?.) before calling forEach on astNode.content.attributes to prevent errors when an element has no attributes.
src/replacer/html.ts	Implemented a filter to skip processing of attributes with a key content of '\r' (carriage return) to avoid issues with newline characters in attribute names.
