Describe the bug

As of writing this issue, I'm seeing new deprecation warnings for the following packages:

npm warn deprecated [email protected]: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated [email protected]: Rimraf versions prior to v4 are no longer supported
npm warn deprecated [email protected]: Glob versions prior to v9 are no longer supported

Upon further investigation, I can see that these deprecated packages stem from recursive-copy@^2.0.14 which hasn't been touched for the past 2 years. recursive-copy is a direct dependency of Eleventy as of the latest canary (3.0.0-alpha.10). Here's a copy of the dependency tree:

@11ty/eleventy 3.0.0-alpha.10
└─┬ recursive-copy 2.0.14 # <-- hasn't been updated, below dependencies are deprecated
  └─┬ rimraf 2.7.1
    └─┬ glob 7.2.3
      └── inflight 1.0.6

Reproduction steps

1. Create a new directory
2. npm init -y
3. npm install @11ty/eleventy@canary
4. See output

Expected behavior

Warnings about deprecated packages should not be thrown.

As an addendum: I recently learned that there's a native API for recursive copying in NodeJS that was introduced back in Node 16 (along with a promisified version too), however even as of v22 it's still labeled as "Experimental", so might not be the right thing to lean on if Eleventy's policy is to only use native API's that are stable. Just thought I'd add it as an afterthought here since it seemed relevant.

Confirmed this, filed upstream first: timkendrick/recursive-copy#44

Lovely visualization here of the dep graph: https://npmgraph.js.org/?q=%4011ty%2Feleventy%40canary#select=exact%3Arecursive-copy%402.0.14

Hmm -- the upstream project seems to have limited activity, and no releases for over 2 years. I think fs-extra could be used instead here... any thoughts? I suspect this would be a breaking change so perhaps best to get into v3 if it's not too late.

@BenjaminEHowe I think we’ll temporarily fork this one and hopefully move to fs.cp in the next major. Looks like fs.cp is stable in Node v22.3.0: https://nodejs.org/docs/latest-v22.x/api/fs.html#fscpsrc-dest-options-callback Filed that work at #3360

We’re now using @11ty/recursive-copy temporarily which includes the npm dependency updates required here: https://github.com/11ty/recursive-copy/

Shipping with 3.0.0-alpha.17.
