Improvements to Grid capabilities, Safari automation, Shadow-DOM support, and more

• Allow more customizations for Grid capabilities:
  -- (This lets you set the browser version on Selenium Grids that support it)
• Add more browser types for local Selenium Grid nodes.
  -- (Opera was added next to Chrome and Firefox)
• Better error messages when converting from XPath to CSS Selectors.
  -- (Only when there are problems with selector-conversion)
• Better compatibility when running automation on Safari.
  -- (innerText is used instead of .text / textContent)
  -- (This change allows Safari to match the behavior seen on other browsers)
• Better compatibility when interacting with Shadow-DOM.
  -- (Wait for visible instead of present as needed)
• Refresh Python dependencies:
  -- pip>=22.0.2;python_version>="3.7"
  -- setuptools>=60.6.0;python_version>="3.7"
  -- charset-normalizer==2.0.11;python_version>="3.5"
  -- pyopenssl==22.0.0;python_version>="3.7"
  -- prompt-toolkit==3.0.26;python_version>="3.6.2"
  -- rich==11.1.0;python_version>="3.6.2"
• Update tests that broke when xkcd.com and pypi.org updated their pages.
