Release 0.2.5 - add app updater

Switches from argparse's builtin --version to some new functions:

• check_latest_release()
• update_dbmenu()

---

• adds a dataclassto Gethub with useful public endpoints to makes the class more useful for querying Github's API for different repos

• adds optional app updates to the -v / --version options

  • uses importlib.metadata to detect the app version from pyproject.toml
  • by default dbmenu can be force updated with pipx with a 2nd option to use pip

• changes the default option to Y for creating the images directory (that holds the standard templates)
