Better help for format function

Browse Source 
Added description of what syntax/parsing engine is used for the formatting. Motivated by https://github.com/qgis/QGIS/issues/42806, but in general a good idea so users can look up more in detail what is possible. Also uniformized spelling (placeholder vs placeholder).
