[ruby-core:91116] [Ruby trunk Feature#15541] Add alias symbolize_keys for symbolize_names kwarg for JSON.parse

Issue #15541 has been updated by shevegen (Robert A. Heiler).


Personally I think that alias name would make sense. With a new alias the backwards
behaviour would also be retained.

When trying to symbolize keys on JSON parsing, it's really hard to remember the name `symbolize_names`:

```
JSON.parse(data, symbolize_names: true)
```

I would like to propose that we change this keyword to `symbolize_keys` to be more clear:

```
JSON.parse(data, symbolize_keys: true)
```

The documentation for this method also reflects the confusion: http://ruby-doc.org/stdlib-2.6/libdoc/json/rdoc/JSON.html#method-i-parse-21

```
symbolize_names: If set to true, returns symbols for the names (keys) in a JSON object. Otherwise strings are returned. Strings are the default.
```

The same issue came up in Psych not too long ago:

I believe the current name causes confusion. Would it be possible to add an alias to this keyword for clarity?
