fix(core): Correct GoogleGenAIIstrumentedMethod typo in type name

Rename `GoogleGenAIIstrumentedMethod` to `GoogleGenAIInstrumentedMethod`
(previously missing an 'n'). The misspelled name is kept as a deprecated
type alias and is still re-exported from `@sentry/core`, so existing
consumers continue to work without changes.

The deprecated alias will be removed in the next major version.
