LaTeX template: Improve readability (#5363)

+ LaTeX template: Improve template readability
  Use `hidelinks` option for hyperref, which has the same effect as `pdfborder={0 0 0}`,
  but its purpose is clearer. Use a simpler conditional for Polyglossia/Babel. Format
  comments more consistently.
+ Update tests
+ Remove hyperref breaklinks option.  According to the documentation, hyperref
  sets this automatically as appropriate to the driver.
