Swift-ify Documentation

[jpsphaxer]

Changes to documentation to align more with DocC.

• Update missed README.md documentation for handling external URLs from previous PR.
• Made some small changes to the project's documentation with hopes to align more with Swift's DocC. Although most are esthetic changes and one outdated doc in the TurboNavigator custom initializer .

You may preview these changes in XCode by Option + Click on element with doc comments.

@joemasilotti I would be interested in maybe creating a Documentation module much like the ones that you can find if you Command + Shift + 0 in XCode.

Thanks for this @jpsphaxer! Turbo Navigator is currently being upstreamed into turbo-ios. I just added a note to the README this morning.

Are you open to migrating this PR on that repo? You can branch off of this PR to ensure everything is up to date.

If not, no worries! Just let me know and I'll manually migrate your changes.
