reintroduce nft + symlink + windows test

[netlify-team-account-1]

in #792, we were able to fix some shortcomings with Symlinks. There's still a bug on windows, and considering our build infrastructure doesn't run windows, we decided to skip that test for the time being:

zip-it-and-ship-it/tests/main.js

Lines 2257 to 2258 in f4e0aef

	'Correctly follows node_modules via symlink',
	['bundler_esbuild', platform === 'win32' ? 'todo:bundler_nft' : 'bundler_nft'],

We should find out what this is caused by, and try to re-enable it.

Note: while our production builds (via buildbot) use Linux, a significant part of our Netlify CLI users are on Windows.

I believe the issue in question only applies to the test suite itself, in the sense that we're using a different method for unzipping the archives to assert their contents.

So the actual functionality for end-users on Windows shouldn't be affected.

@netlify-team-account-1 can you confirm this is the case?

Ah ok @eduardoboucas, thanks for the precision. This makes sense!

[netlify-team-account-1]

It's two-fold. Our test suite has problems unzipping symlinks, so we're skipping that test. This also means that the suite currently cannot verify that symlinks are correctly taken into account on windows, so the suite doesn't ensure there's no problems for end-users on Windows. Considering Symlinks are already a bit of a weird thing on windows, I'd say this uncertainty is acceptable for now.
