gff_tigrinya_eritrea should use ti-ER for its BCP 47 tag

[mcdurdin]

Because this keyboard is distinct from gff_tigrinya_ethiopia, it should have the region in the keyboard BCP 47 tag

[DavidLRowe]

@mcdurdin So, if I understand correctly, ti should change to ti-ER in .keyboard_info, and there should be an addition to the .kps file to add ti-ER as well.

[mcdurdin]

@DavidLRowe, yes that is correct, although the change to the .kps is not strictly necessary until we start deployment of .kmp files to Android/iOS (soon).

Small note: in terms of workflow, it's better to close an issue when the PR is merged. You can do this automatically by using certain keywords in a PR comment, for example "fixes #158"

I've updated the PR to show this -- you can hover over the word 'fixes' to see the action that will occur when the PR is merged :)
