TypeError: this.customTesters is not iterable in expect.jsonContaining in jest 29.4.0

[justin-tay]

After upgrading jest to 29.4.0. Using expect.jsonContaining triggers the following error TypeError: this.customTesters is not iterable.

I suspect this is likely due to changes from jestjs/jest#13654.

jest-json-matchers/index.ts

Line 75 in 469552f

return toMatchJSON.call(expect.getState() as MatcherState, received, jsonObject)

I think that instead of using expect.getState() the this variable is expected to be passed through.

Thanks for your report @justin-tay. I will have a look later today.
