Update dependencies, and require Node >= 20

Hey @kategengler, @stefanpenner, long time no speak!

In this PR, I'm updating the minimatch dependency to ^10, which changes the TypeScript interface slightly from IMinimatch to Minimatch in places where minimatch instances are allowed. Since Minimatch 10 requires Node >=20, this PR also requires Node 20 as the minimum version. (All previous Node versions are EoL at this point.)

Do either of you have an opinion or hunch on whether this kind of change warrants a major version bump in walk-sync? In other words, do you think I can publish this as 3.1.0 without making people unhappy, or do you think I should bump to 4.0.0?

👋 It's nice to hear from you @joliss!

We do have versions of packages out in the wild with deps on ^3.0.0 of walk-sync that support older nodes than 20, so I think the safer way to go would be a major bump.

Lovely, that's very helpful @kategengler! I'll push this as 4.0.0.

Hope everything's well!
