Make it more clear the use of Google Firebase to send crash reports

Expected behaviour

Being transparent about the use of a Google framework to send crash reports.

Expected footer label:
"Nextcloud iOS uses Google Firebase for the analysis of a crash. Your personal information is not sent with the report. If you want disable it, please change the setting "Disable crash reporter" to ON"

Actual behaviour

The App shows a vague description of the framework used to send crash reports.

Currently shown text:
"Nextcloud iOS uses a service for the analysis of a crash. Your personal information is not sent with the report. If you want disable it, please change the setting "Disable crash reporter" to ON"

Steps to reproduce

1. Open the App
2. Press the tab "More"
3. Select the option "Settings"
4. Select the option "Advanced"
5. Check the footer label on the option "Disable crash reporter"

Reasoning or why should it be changed/implemented?

A lot of people use Nextcloud to avoid being tracked in any way by Google services. For the users to make an informed decision, the fact that the App uses Google Firebase for crash reporting should be clearly communicated to them.

Start with the English localization entry linked at iOSClient/Supporting Files/en.lproj/Localizable.strings around line 326, then follow the More > Settings > Advanced path to confirm where the footer appears. Update the label to clearly name Google Firebase and preserve the crash-reporting and opt-out information; verify the wording in the Disable crash reporter setting.
