support(windows): Tigrigna keyboards appear in Keyman Configuration, but not taskbar menu

### Describe the bug

This is a weird one... the net result is that I have 3 Tigrinya keyboards installed (2 ti-Er, 1 ti-ET) as shown below:

And only 1 appears in the Keyman taskbar menu for selection -and it is the Windows system keyboard for Tigrinya Ethiopia (which I didn't install), not one of the above 3:

These screenshots are taken after a reboot.

### Reproduce the bug

1. I removed the "Tigrinya (Eritrea)" language support (which includes the system ti-ER keyboard) under "Settings > Time & Language > Language & region", oddly, the keyboard remained in the menus, even after a restart.
2. Installed the GFF Tigrinya-Eritrea keyboard. It does not appear in the keyboard, but the system keyboard remains.
3. Repeat 2, same result.
4. Repeat 2, same result.
5. Installed the GFF Tigrinya-Ethiopia keyboard. It does not appear in the menus, but now GFF Tigrinya-Eritrea _does_ appear. GFF Tigrinya-Eritrea is under a [TI] icon along with the system Tigrinya-Eritrea keyboard.
6. Install the Geezword Tigrinya keyboard. Now, no Tigrinya keyboards appear in the menus, except for the system keyboard which is now "Tigrinya-Ethiopia" (this may have appeared on step 5, and I misread the name). The other 3 Tigrinya keyboards appear in the menus (see attached photos).
7. Returning to "Settings > Time & Language > Language & region", "Tigrinya (Eritrea)" has returned, and there is no entry for "Tigrinya (Ethiopia)" that would go with the system keyboard that has appeared.
