Update to latest version of Ionicons

[jahnagoldman]

Current only supports v5.0.1, but Ionicons is up to 5.5.2 at this point.

Could you please update to be able to use the latest version as there seem to be a lot of icons that are unable to be used because of this. Thanks!

EDIT

Sorry! Just found this issue and realized it's just that the README is incorrect. #1299. Looks like Ionicons is only a little ahead at this point (5.5.2 vs 5.4.0), so could be updated but not sure if there's any significant enough difference at that point.

Could the README still get updated though to reflect the correct supported versions of each icon library?

I created this PR to update to the latest version of Ionicons #1484 .
While waiting for it to be merged, you can use this in your package.json
"react-native-vector-icons": "mrkpatchaa/react-native-vector-icons#ionicons-v6"
I hope this helps.
