chore: update sharp to ^0.21.0

[WaylonWalker]

This will help folks having installation issues on windows resolve without opening an issue. This issue has been seen in Issue lovell/sharp#1382, lovell/sharp#1387, and in #8325.

Bumping sharp from ^0.20.2 to ^0.21.0 should deal with the underlying cause.

Thanks @lovell! Is there any breaking changes we should worry about?

[lovell]

Based on a quick scan of the gatsby-plugin-sharp source there is one deprecation that will affect you. The following change would be required to avoid warnings:

-    .resize(options.width, options.height)
-    .crop(options.cropFocus)
+    .resize(options.width, options.height, {
+      position: options.cropFocus
+    })

@WaylonWalker would you be up for bumping sharp version and adjusting gatsby-plugin-sharp code?

@pieh I attempted, but am getting confused with some of the errors. I worked through the ones that seemed obvious to me. Some things seem unrelated, some seem related to node versions (testing setup??). Probably doesn't help that I am on a 40 kbps network at the moment, and working from the github ui only..

Dependency changes are hard to test currently, I will get on it - thanks for doing what You already did!

[WaylonWalker]

Thanks @pieh, it looks very tricky. Especially not being too familiar with the codebase. Let me know if there is anything else I can do.

@WaylonWalker looks like the commit histories are a little screwy. Trying to iron it out, and then I'll test this locally. Thanks for your patience!

Well this was fun! 😅 I somehow managed to wipe the history, but I should have all the commits (and a successful merge) in WaylonWalker#1, so once we merge that we can re-open this!

Also so thankful for git reflog 🙏
