useful in a wider context.

* For #6308: Remove unecessary telemetry

* For #6308: Bump expiry date on telemetry

This reverts commit 93122b61.

* For #3088: add translation pruning Py scripts from Focus

The only change made was updating "Focus/Klar" to "Fenix"

* For 3088: call translation pruning scripts during release builds

* For 3088: fix filter-release-translations.py

Moving it into Fenix introduced one additional layer of nesting, which was not accounted for in a relative path.  🤦

* For 3088: comment about the risks of modifying source

* For 3088: updated locales.py to read from l10n.toml

Also removed some previously unused properties from locales.py

* For 3088: added error handling to script in locales.py

* For 3088: updated locale parser per review comments

Added two new sources to be counted ('widget' and 'shortcut') besides 'action' and
'suggestion'. Also modified/fixed some tests.
