Replace underscore with lodash in env folder

Closes #196673

See merge request gitlab-org/gitlab!27160

- replaced underscore functions with lodash equivalents
- moved chain to flow as the babel plugin for lodash
  does not support chain
- used composition instead https://medium.com/making-internets/why-using-chain-is-a-mistake-9bc1f80d51ba
- used partial right for sortBy
  https://stackoverflow.com/questions/56324387/jest-throwing-typererror-expected-a-function-when-using-lodash-pipe-flow
- escape, isFunction, isUndefined, isNull, omit, chain, isEqual,
  and isEmpty

so they will still be available when MR's target branch changes.

This will be useful when FE starts to filter rules on MR create.

Remove rspec-set gem

Closes #27922

See merge request gitlab-org/gitlab!28282

We've removed all instances of `set` and have moved them all over to
use `let_it_be`

This does update the schema, but does not require large updates in the frontend, as opposed to Types::BigInt which would require string -> number casting. 
GraphQL-induced type casting should prevent type issues according to https://spec.graphql.org/June2018/#sec-Float

The values allowed in this type should suffice for the foreseeable future.

Also  updated the changelog to document this limitation.

This would currently fail due to graphql-constraints on integer types (which is of range -2^31 .. 2^31-1)

INT_TYPE can only hold 2**31 (?), which is not enough for large projects and root namespaces.

Replace set to let_it_be in ee/spec
