There are a couple of hardcoded UA checks targeted at iOS endpoints
introduced circa 2.2-beta. One of those pops up an "unsupported" toast
when the device joins a conference - the other blocks camera
sharing.
Those checks are outdated since we transitioned to minBrowserVersions
approach that redirects the client to an unsupported view upon join. I
also assume the checks are bugged since, in some environments, it flags
iPadOS endpoints as iOS and version-checks it to a hardcoded "12.2"
threshold (which is incompatible with iPadOS versioning). That caused
camera sharing not to work, which is a false negative.
I consider the checks to be outdated, so I removed all references to
them.
