Update Local Resolvers documentation wording

[bignimbus]

Context:

• updates local resolver warning #10062
• Remove Local resolver support from the core of Apollo Client #10061
• Release local resolvers back into the link chain #10060
• Feature: Opt-in to including Apollo Client local resolver code in your bundle #8189

When #10060 is closed, Local Resolver functionality will still be supported by the Apollo team, albeit in a different form. We updated the Local Resolvers documentation recently to reflect our plans for Local Resolvers. A few suggestions for further updates:

• Remove (deprecated) from the heading
• Edit the ⚠️ DEPRECATION WARNING section as follows:
  • Replace ⚠️ DEPRECATION WARNING with NOTE
  • Current wording could be interpreted that we might remove Local Resolvers from Apollo Client before we ship an analogous ApolloLink implementation. New wording should make it clear that we plan to continue to support Local Resolver functionality continuously without a gap between removing it from core and adding a new implementation
