clang: fix typo availbility

[sloorush]

Summary

• Fixes #56787.

I am fixing the spelling of availability.

I am unsure if this change will have any side effects. If someone can help on how to check if it has any side effects, I can test those out as well.

LGTM. Could you please provide your real name and email address, like Name <[e-mail]> ? So that I can commit this for you. Also feel free to ask for commit access.

@inclyc, Here is my real name and email address in the requested format:

Aarush Bhat <[e-mail]>

I would love to get commit access. What exactly is the process? Do I have to email as mentioned in https://llvm.org/docs/DeveloperPolicy.html#obtaining-commit-access?

Don't worry! Just feel free to send the email to Lattner, he is very fine.

Okay! I'll drop them an email. Thank you for committing the change on my behalf!

Copied from github comments:

Thanks for working on this, changes on serialization may still cause issue related to backward compatibility. Even though this patch passed all regression tests, if in the future some one reports clang must give availbility (typo), we may have to revert this change.

clang/lib/ExtractAPI/Serialization/SymbolGraphSerializer.cpp

SymbolGraphSerializer::serializeAPIRecord(const RecordTy &Record) const {
   Object Obj;
   serializeObject(Obj, "identifier",
                   serializeIdentifier(Record, API.getLanguage()));
   serializeObject(Obj, "kind", serializeSymbolKind(Record, API.getLanguage()));
   serializeObject(Obj, "names", serializeNames(Record));
   serializeObject(
       Obj, "location",
       serializeSourceLocation(Record.Location, /*IncludeFileURI=*/true));
-  serializeObject(Obj, "availbility",
+  serializeObject(Obj, "availability",
                   serializeAvailability(Record.Availability));
   serializeObject(Obj, "docComment", serializeDocComment(Record.Comment));
   serializeArray(Obj, "declarationFragments",
                  serializeDeclarationFragments(Record.Declaration));
   // TODO: Once we keep track of symbol access information serialize it
   // correctly here.
   Obj["accessLevel"] = "public";
   serializeArray(Obj, "pathComponents", Array(PathComponents));
