Update toolchain and doc for 6.2 (#564)

In preparation for the 2.0.0 GA release,

- Update `.swift-version`, `Package.swift` and all examples'
`package.swift` to Swift 6.2
- Update all references to `2.0.0-beta.3` to `2.0.0`. This includes the
doc and readme, but also the dependencies in the examples
`Package.swift`. This will temporary break the build of the examples,
until we tag v2.0.0. Note the CI will not be affected as its consumes
the local version of the library
- [CI] Use Swift-6.2-noble for all testing tasks
- Reinstate the script to generate the contributors list and update the
list
