[Bug] opened_link telemetry is wrong: reports twice when it should report once on cold app link

[mcomella]

Steps to reproduce

• (ensure telemetry is enabled in your build)
• Force-stop the app
• Click a link in another app (I used gmail)
• Send ping to glean debug view (adb shell am start -n org.mozilla.fenix.debug/mozilla.telemetry.glean.debug.GleanDebugActivity --es tagPings correctness --es sendPing events)
• Check ping in debug view for results

Expected behavior

opened_link appears once

Actual behavior

opened_link appears twice

Device information

• Android device: P2
• Fenix version: master fd90afc

---

Note: the app_opened_all_startup captures app startup (i.e. app background to foreground) and includes if the link came from app_link. As a solution to this issue, assuming I understand the probe correctly, we could merge the NORMAL/PRIVATE state to the app_opened_all_startup probe to get the same results.

If you correct the existing probe, don't forget to:

• increment the version number
• Undo the doc changes in For #14133: warn opened_link telemetry may be wrong. #14138 that claim this probe may be incorrect

I opened #14138 to update the docs with the info that this probe may be wrong.
