Creating fret diagrams with chord names but no staff/staves using fret diagram markup

This snippet shows how to create fret diagrams with chord names but no staff/staves, for a fret diagram which is not one of the predefined fretboard diagrams i.e. with the fret diagrams specified using fret diagram markup.

For more info, please see:

• https://lilypond.org/doc/v2.24/Documentation/notation/common-notation-for-fretted-strings#predefined-fret-diagrams (“It is common that both chord names and fret diagrams are displayed together.”)
