maint: attempt to fix repeated HTTP 202

[yozachar]

Change log

• removes http:// & https:// retry mount from request session
• removes request session (corrupt cookies might cause trouble)
• uses fake user-agent for each fresh requsts (new depns)
• updt. deps, adds SAST dev deps - bandit

Note

Before merge, if you wanna test, change the workflow line to - uses: joe733/waka-readme@workshop. If it's working after tests, you can react 👍🏻 to this thread, else comment below. Change it back to - uses: athul/waka-readme@master to avoid nasty surprise if the forked-branch workshop disappears.

PS

• Manual tests are working fine.
• Maximum waka-readme action runtime is ~300s
• Larger time range seems to take around 10 - 30 min for completion.

potentially fixes #91
