python3-pyproject-metadata: upgrade 0.7.1 -> 0.8.0

PYPI_PACKAGE is updated since the upstream now uses an underscore in the
package name.

Changelog (https://pep621.readthedocs.io/en/stable/changelog.html#id1):

  - Support specifying the metadata_version as 2.1, 2.2, or 2.3
  - Always normalize extras following PEP 685
  - Preserve the user-specified name style in the metadata. .canonical_name added to get the normalized name
  - Require “version” in the dynamic table if unset (following PEP 621)
  - Support extras using markers containing “or”
  - Support empty extras
  - Using .as_rfc822() no longer modifies the metadata object
  - Fix email-author listing for names containing commas
  - Separate core metadata keywords with commas, following the (modified) spec
  - An error message reported project.license instead of project.readme
  - Produce slightly cleaner tracebacks Fix a typo in an exception message
  - Subclasses now type check correctly
  - The build backend is now flit-core
