[orchestra2md] invalid handling of more than one appinfo about tablature

[donmendelson]

For documentation, some headings are considered equivalent so they are combined, e.g. "documentation" and "description". Furthermore, they are ranked so synopsis always comes before elaboration, etc. Anything with unknown purpose is given the lowest rank. However, that logic does not apply to appinfo; every purpose must be considered unique, and there is no preset ranking.

[donmendelson]

Setting sequence so all appinfo follows documentation is their set order by purpose.

Corrected appinfo columns:

|----:|----------|----------|---------|---------|
| 454 |          | optional |         |         |
| 455 |          | optional | [Hanno] | [Klein] |
| 456 | EXXXXX   | optional |         |         |
