add py310 (#4270)

* chore: adding py310 to ci

though this will require code/parser changes, this is to prepare for
upcoming adoption

* fix: set python version as string

* fix: reference to master -> main

* fix: coverage is not reported in master

- disable amalgamation
	1. during coverage report tests
	2. qa tools like mypy may follow imports
- use python 3.9 for coverage and qa report. since it will have more
coverage and better typing support

* chore: use py3.10 with setup-py action

* chore: add news-item check job

* fix: py3.10 error while starting

the match statement is not supported.
while the syntax support is only upto py3.8

* fix: news-item checker

* chore: enable fail report for py310 tests

* test: add test for ptk_shell
