GF Latin African: Remove ɾꞨꞩ

[moyogo]

• ɾ is not used in orthographies, only phonetic notations
• Ꞩ, ꞩ: not adequate for orthographies, Unicode 16.0 Ꟍꟍ (U+A7CC, U+A7CD) to be used in Cupeño and Luiseño instead. See https://www.unicode.org/L2/L2022/22113r-two-latin-chars.pdf

Thank you, @moyogo.
We have reviewed this, and in anticipation of some other cases to emerge, it was suggested to create instead an SSA Latin branch, merge all these PRs to that branch, and when work is complete on re-definitions, create PR to merge them to the main.
Could you please change the PR that way?

@vv-monsalve Is this correct: SSA-Latin?

For the branch name? Yes, I think so. It's only temporary and will eventually be merged into the main, so it's ok.
