[meta] Update JavaScript dependencies for Drupal 9.5

Tagging for another round of updates during the rc, but we're done for 9.5.0-rc1 now!

Added child issue #3324378: Update JavaScript dependencies for Drupal 9.5

As of today, yarn outdated on Drupal 9.5 shows this:

Package     Current Wanted Latest Package Type    URL                                                           
chalk       4.1.2   4.1.2  5.1.2  devDependencies ...                 
farbtastic  0.0.0   exotic exotic devDependencies .../1.3u.tar.gz  
joyride     0.0.0   exotic exotic devDependencies .../v2.1.tar.gz
nightwatch  1.7.13  1.7.13 2.5.3  devDependencies ...                        
shepherd.js 9.1.1   9.1.1  11.0.0 devDependencies ...                          
tabbable    5.3.3   5.3.3  6.0.1  devDependencies ...

None of these have newer releases within the same major versions, and we don't want to raise the major version for Drupal 9, so postponing this issue until there's something to update. Not marking it fixed or closed though, since we'll still want to check again prior to releasing 9.5.0.

New updates in #3325114: Update to the latest cspell, eslint, postcss-import, stylelint. terser and webpack-cli version

Drupal 9.5.0-rc2 was released today, and the stable release is scheduled for Dec. 14.

As of today, yarn outdated returns:

Package           Current Wanted Latest
chalk             4.1.2   4.1.2  5.2.0                
eslint-plugin-yml 1.2.0   1.3.0  1.3.0           
farbtastic        0.0.0   exotic exotic
joyride           0.0.0   exotic exotic
nightwatch        1.7.13  1.7.13 2.5.4                                   
postcss-import    15.0.1  15.1.0 15.1.0           
prettier          2.8.0   2.8.1  2.8.1                                    
shepherd.js       9.1.1   9.1.1  11.0.0                                 
tabbable          5.3.3   5.3.3  6.0.1

Filtering out major version updates (which we wouldn't do for Drupal 9 without a compelling need to) gives us:

Package           Current Wanted Latest
eslint-plugin-yml 1.2.0   1.3.0  1.3.0           
farbtastic        0.0.0   exotic exotic
joyride           0.0.0   exotic exotic
postcss-import    15.0.1  15.1.0 15.1.0           
prettier          2.8.0   2.8.1  2.8.1                                    

Farbtastic and Joyride are up to date per #15, which leaves us with:

Package           Current Wanted Latest
eslint-plugin-yml 1.2.0   1.3.0  1.3.0           
postcss-import    15.0.1  15.1.0 15.1.0           
prettier          2.8.0   2.8.1  2.8.1                                    

Those are the same 3 as discussed in #3258933-61: [meta] Update JavaScript dependencies for Drupal 10, so I'm marking this issue as Fixed for the same reason as there. One unique concern we might want to consider is that 9.5 will be the final minor version for Drupal 9, so while we can do the above in Drupal 10.1, we might not be able to for Drupal 9. I'll double check with release managers to make sure we're ok with either doing these in 9.5 patch releases or not doing them, but marking this Fixed in the meantime anyway because I think the answer will be yes.
