chore(ios): renames problematic app selectors

When working on a new build script, I tripped over the `-?` question
mark help parameter here, as it needs to be escaped. Opted to fix all
the instances in our scripts, although AFAICT there would not have been
current bugs arising from this, as there were no conflicting one
character options lower in the case list.

change(ios): minimum iOS version -> 12.1

chore(ios): dependencies - update sentry-cocoa to 6.2.1

auto: increment master version to 15.0.57

Building km-config now requires an additional step so that
generates `lang_tags_map.py`. During a package build this happens in
`reconf.sh`. This change updates the documentation, and also adds
this build step to the Makefile, so that the file gets generated
when building from the command line.

Closes #5074.
