Specify date-fns 2.x

[drewbrend]

Same as #262 but has the lockfile updated for CI to pass.

This should fix #260 for date-fns-tz v2 which will still be an issue even when date-fns-v3 is released.

Example where this will still be an issue after v3 is supported (real scenario from my company):

• shared-library-1 uses date-fns v2 and date-fns-tz v2 (sure they could upgrade, but haven't yet)
• shared-library-2 uses date-fns v3 but does not use date-fns-tz or shared-library-1 so they have no issue
• some-app uses shared-library-1 and shared-library-2
• date-fns-tz v2 (as a dependency of shared-library-1) will attempt to use v3 because it is available and satisfies >=2.0.0
• some app will throw an error despite not even using date-fns directly

Came to say we've been bitten by this :) Thanks for the PR @drewbrend !

Thanks for the approval! Do I need to do anything to have this merged and released?

Just came here to say that i was experiencing issues because of this

I am adding my support for this to be merged and released. It would be massively helpful to mark this package v2 to only install the proper date-fns v2 versions.
