Description

• Miscellaneous typo and punctuation fixes.
• Adjusted emphasized lines of example code blocks in the tutorials; many were misaligned most likely due to changes to the underlying .py files which were not reflected in the docs.
• Modified descriptions of SQLAlchemy repository functions in the docs to be more consistent with each other.
• Updated links to external Real Python articles to use hyperlinked article names instead of raw URLs.
• No code changes, pre-commit was run before pushing.
