Update globby to v11.1.0

[Lehoczky]

Hi Tim,

I've recently run into an issue relating to the old globby version this package uses. I've cloned the repo, updated globby to v11.1.0 and every test is passing on my machine (win 10, node 16):

> mocha --recursive test



  gh-pages
    main
      ✔ --dist lib
      ✔ --dist lib -n
      ✔ --dist lib -f
      ✔ --dist lib -x
      ✔ --dist lib --dotfiles
      ✔ --dist lib --dest target
      ✔ --dist lib -a target
      ✔ --dist lib --git path/to/git
      ✔ --dist lib --user Full Name <email@example.com>
      ✔ --dist lib --user email@example.com
      ✔ --dist lib -u Full Name <email@example.com>
      ✔ --dist lib --before-add C:\Users\ifjle\Projects\gh-pages\test\bin\fixtures\beforeAdd.js
      ✔ --dist lib -u junk email (user error)

  basic usage
    ✔ pushes the contents of a directory to a gh-pages branch (1651ms)
    ✔ can push to a different branch (1729ms)

  the beforeAdd option
    ✔ runs a provided async function before adding files (1985ms)

  the dest option
    ✔ allows publishing to a subdirectory within a branch (1954ms)

  the src option
    ✔ can be used to limit which files are included (1860ms)

  the remove option
    ✔ removes matched files in remote branch (1703ms)
    ✔ skips removing files if there are no files to be removed (1434ms)

  index
    getCacheDir()
      ✔ works for git@github.com:<username>/<project>.git
      ✔ works for https://github.com/<username>/<project>.git
      ✔ works for https://<username>:<password>@github.com/<username>/<project>.git

  util
    byShortPath
      ✔ sorts an array of filepaths, shortest first
    uniqueDirs
      ✔ gets a list of unique directory paths
      ✔ gets a list of unique directories on absolute paths
    dirsToCreate
      ✔ gets a sorted list of directories to create
    getUser
      ✔ gets the locally configured user (309ms)

Would you accept a PR related to this change? Or is there a particular reason why gh-pages is using such an old globby version?
