Bug Fix : This PR fixes a bug in rtl_ltr_linter.py where the script incorrectly processes <div> tags.

The Bug:
The lint_file function uses continue statements after detecting an opening or closing <div> tag. This causes the linter to stop processing the rest of the line, which leads to a problem if a single line contains both an opening and a closing tag, like <div dir="rtl">Some Text</div>.

This bug can make the block_context_stack inconsistent, which may result in incorrect linting of subsequent lines and lead to false positives.

The Fix:
I have refactored the code to handle all <div> tags on a single line. Instead of using continue statements, the script now finds all <div> tags on a line and processes them in order, ensuring the block_context_stack remains accurate. This fix is a minor change that improves the linter's reliability without affecting its core functionality.
