`RSpec/ExpectActual` autocorrects unsafely given a hash and a matcher without brackets

[boardfish]

Given this input, for example:

expect({ a: 1 }).to eq something_else

RSpec/ExpectActual autocorrects to this:

expect(something_else).to eq { a: 1 }

This isn't interpreted correctly by Ruby, which returns:

syntax error, unexpected ':', expecting '}' (SyntaxError)

Safe output for this cop would be:

expect(something_else).to eq({ a: 1 })
