Bundled Themes: Bump version numbers for 6.1.

In coordination with the release of 6.1, a new version of each bundled theme will also be released. This bumps the version of each theme to the following:

• Twenty Ten: 3.7
• Twenty Eleven: 4.2
• Twenty Twelve: 3.8
• Twenty Thirteen: 3.7
• Twenty Fourteen: 3.5
• Twenty Fifteen: 3.3
• Twenty Sixteen: 2.8
• Twenty Seventeen: 3.1
• Twenty Nineteen: 2.4
• Twenty Twenty: 2.1
• Twenty Twenty-One: 1.7
• Twenty Twenty-Two: 1.3

Additionally, this audits all $version parameters for wp_(enqueue|register)_(script|style) calls, ensuring accurate last edited or theme version values for proper caching and cache busting.
