Update pkg/repo names in deprecation messages (#41618)

Summary:
Several deprecation warning messages related to components that were removed from `react-native` were outdated.
Some repositories have been moved, some packages were renamed/re-published under new names. A couple **never existed** (`react-native-community/segmented-checkbox` and `react-native-community/react-native-image-picker`).

This updates all messages to include links to the latest repositories and references to npm packages.

Because `react-native-community/art` is deprecated I've also slightly amended the message with the suggestion from its [repo readme](https://github.com/react-native-art/art#deprecated---this-package-is-deprecated-if-you-need-a-similar-package-please-consider-using-react-native-svg).

## Changelog:

[GENERAL] [FIXED] - Update pkg/repo names in deprecation messages

Pull Request resolved: #41618

Test Plan: No code change, just documentation/text.
