Missing static HTML files in pip installation

[yalfg]

Describe the bug
The generation of a static HTML report fails with an exception due to a missing HTML static file in the pip installation.

CodeChecker version
6.18.0, installed using pip3.

To Reproduce
Just try to generate an HTML report from a previous analysis, for example:

CodeChecker parse -e html -o html_report ./pfiles

This will fail with a python exception.

Expected behaviour
Successful creation of an HTML report.

Desktop (please complete the following information)

• OS: Debian Linux Buster or Bullseye

Additional context
When installing 6.18.0 using pip3, the HTML static files directory is missing. It should be under:
site-packages/codechecker_report_converter/report/output/html/static.
This cause the parsing with export to HTML to fail with an exception as it can't find static/layout.html.
