Add string data to bowed string instruments, to allow for Tablatur notation

Your idea

Add string data (number and tuning of strings, 'max. fret' reflecting the strings' range) to bowed string (violin, viola, cello, etc.) instruments, to allow for Tablatur notation

Problem to be solved

Having string date on bowed string instruments (violin, viola, cello, etc.) would allow to create tablature staves for them.

Prior art

The string quartet template has string data embeded.
These may server as the source for some of these additions to instruments.xml

• Violin I: https://github.com/musescore/MuseScore/blob/f982d405e0a761938477e9671d0f6e645aa1f51d/share/templates/03-Chamber_Music/01-String_Quartet/01-String_Quartet.mscx#L56-L62
• Violin II (same as Violin I): https://github.com/musescore/MuseScore/blob/f982d405e0a761938477e9671d0f6e645aa1f51d/share/templates/03-Chamber_Music/01-String_Quartet/01-String_Quartet.mscx#L137-L143)
• Viola: https://github.com/musescore/MuseScore/blob/f982d405e0a761938477e9671d0f6e645aa1f51d/share/templates/03-Chamber_Music/01-String_Quartet/01-String_Quartet.mscx#L220-L226
• Violoncello: https://github.com/musescore/MuseScore/blob/f982d405e0a761938477e9671d0f6e645aa1f51d/share/templates/03-Chamber_Music/01-String_Quartet/01-String_Quartet.mscx#L302-L308
  this one is also useful for plucked bass...

Additional context

This would need to be done in that (in)famous Excel sheet (outside the GitHub Repo), that the instruments.xml is generated from

Compare the string data in the String Quartet template entries for Violin I, Violin II, Viola, and Violoncello with the instrument definitions generated into instruments.xml. Start by finding the external Excel sheet and its generation workflow; done means bowed-string instruments include string count, tuning, and maximum fret data so tablature staves can be created.
