Tag the matching commits against the currently supported versions of React Native

[blakef]

Problem

We need accurate tags in the project for the currently supported versions of React Native, so the CLI can match and initialise the correct template. These might, in-fact, be the same commits but we need to be sure.

Currently supported versions

See here, but the list is:

Version	Type	Support level
0.74.x	Next version	Future
0.73.x	Latest stable	Active
0.72.x	Previous (-1) minor series	Active
0.71.x	Previous (-2) minor series	End of Cycle
<=0.70.x	Old minor series	Unsupported
