DEPRECATION warning ahead of pip 22.2

[rmb-wdc]

Hi,

Running pip==22.0.2 against a local pi library created with pip2pi==0.8.2 generates a series of deprecation warnings, one for each new package that is installed. The implication is that pip>=22.2 will refuse to work with libraries created with pip2pi==v0.8.2.

DEPRECATION: The HTML index page being used (file:///path/to/package/index.html) is not a proper HTML 5 document. This is in violation of PEP 503 which requires these pages to be well-formed HTML 5 documents. Please reach out to the owners of this index page, and ask them to update this index page to a valid HTML 5 document. pip 22.2 will enforce this behaviour change.
