Update FSharp.Core to use array instead of []

[edgarfgp]

Now that #13700 merged. As part of this PR we will update FSharp.Core

@vzarytovskii I have updated for now only array.fs . Not sure if we want to update all of the instances where we use [] to use array ? . Happy to do it as part of another PR :)

@edgarfgp -
If we think this is the correct way to format array type definitions, wouldn't it be preferable to implement them using fantomas so that we can police it, rather than providing a thousand manually edited PR's?

[vzarytovskii]

Hm, to be completely honest, I'm not sure we should update everything now.

As per fsharp/fslang-suggestions#635 (comment) - the most important places are tooling presentation (addressed in the original PR), API reference and docs.

Yep, agree, I think if we want to unify it, we should enforce it.

@vzarytovskii @KevinRansom Thanks for the feedback. Agreed Fantomas is a better approach to do this :) . happy to help either way . Closing this PR
