chore(deps): bump CLI version to 7.0.3 to address web debugging issue (#33156)

Summary:
Doing this patch level bump to ensure that all packages consuming `react-native` will get `7.0.3` and not lower 7.x versions.
This is because this new patch contains this fix:  react-native-community/cli#1560
(thanks NickGerleman & thymikee for your work!)

We'll have to cherry-pick this into the 0.68 branch.

While at it, I've also done a cheeky `npx yarn-deduplicate` to clean up the `yarn.lock` a bit.
