fix: update HTML tags to lowercase in formatStepContent function

[danhellem]

This pull request updates the formatStepContent function in src/tools/test-plans.ts to improve the HTML output generated from Markdown content. The main change is to use standard lowercase HTML tags instead of uppercase tags for formatting, ensuring better compatibility and adherence to HTML standards.

Formatting improvements:

• Changed the Markdown-to-HTML conversion to use lowercase tags (<b>, <i>, <u>, <code>, <a>) instead of uppercase tags (<B>, <I>, <U>, <CODE>, <A>), which aligns with HTML best practices and improves rendering consistency.
