Fix tables and units

- Adds custom CSS for `text-left` and `text-right` classes.  These are
  added to table cells by MyST parser but are not defined in Boostrap 5.
  [issue](executablebooks/MyST-Parser#785)

- Converts the post-lab model parameters table from a list-table to a
  regular table because list-tables do not support column alignment.

- Replaces the deprecated \si command with \qty.  Hopefully this will
  help with compatibility with the LaTeX siunitx package.
