Remove dependency on rifraf and make 11ty 18% smaller

Is your feature request related to a problem? Please describe.

I love 11ty, it's fast and lightweight, but it's still relatively big - my simple blog has 50MB of files in node_modules/, which is insane!

Simplifying the dependency tree would help reduce the risk of supply chain attacks, makes installs faster and is better for the environment. I'd be happy to work on this, but I think it would require some coordination to make we don't break semver.

Describe the solution you'd like

Remove outdated dependencies like 'polyfills' and other long dependency chains in-line with 11ty's minimum node version of 18.

npmgraph is a great site to visualize the dependency tree, I see a few areas with easy wins.

@11ty/recursive-copy depends on this package 'rimraf', which adds 4MB of dependencies, just to delete directories (this has been built in since NodeJS 12, which is way below the minimum Node version 18 required for 11ty today)

Fixing this should just be swapping to fs.rmdir in 11ty/recursive-copy

This is the single largest dependency chain in 11ty, and also looks like it brings in the most unrelated packages. Considering how simple it looks to remove, I think it would definitely be worth trying to get rid of.

I've already done this so far:

• Remove dependency on object.entries to make 11ty leaner eleventy-posthtml-urls#1

Describe alternatives you've considered

This has a similar effect to #3360, but doesn't require a minimum NodeJS bump.

Sounds like another item for housekeeping label :-)

You can vote on issues like #3167 to help prioritise these updates.

Would welcome a PR to https://github.com/11ty/recursive-copy 🙌🏻 these suggestions are great!

Notably, this would be a breaking change for 11ty/recursive-copy but not 11ty/eleventy 👍🏻

I think fs.rm is the one you want though? (not fs.rmdir)

[jeffalo]

Done! It looks like it works at a first glance (passes all 59 tests), but I'm not sure if there's anything else I can/should test.
