Windows: Make the `Ctrl+RightArrow` key accepts the next suggestion word in addition to its default by-word movement.

[sangafabrice]

PR Summary

• Modify the NextWord handler to accept the next suggestion word for consistently using the Ctrl+RightArrow key
• The Ctrl+RightArrow now moves the cursor word-by-word for both editing the line and accepting suggestions
• Before, the NextWord handler did not operate on the suggestion text when the cursor was at the end of the line
• NextWord is now an alternative to the less consistent custom binding ForwardCharAndAcceptNextSuggestionWord defined in the SamplePSReadlineProfile.ps1 script
• ForwardCharAndAcceptNextSuggestionWord is less consistent because it mixes word movement, line movement, and character movement in a single key
• NextWord is now consistent because the Ctrl+RightArrow key moves the cursor uniformly in the editing and suggestion cases
• Documentation is not needed at PowerShell-Docs because NextWord is not in the list of the advertised functions
• This commit is a feature addition, and it does not impact the previous use of the Ctrl+RightArrow key in Windows
