This PR makes `Prism` warn `&` interpreted as argument prefix.
This carries a similar meaning to the following Ruby warning:
```console
$ ruby -cwe "foo &bar"
-e:1: warning: `&' interpreted as argument prefix
Syntax OK
```
Previously, it did not issue a warning:
```console
$ bundle exec ruby -rprism -ve "p Prism.parse('foo &bar').warnings"
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
[]
```
From now on, it will issue a warning similar to Ruby's:
```console
$ bundle exec ruby -rprism -ve "p Prism.parse('foo &bar').warnings"
