[ruby/prism] Fix parser translator tokens for backslashes in single-quoted strings and word arrays

These are not line continuations. They either should be taken literally,
or allow the word array to contain the following whitespace (newlines in this case)

Before:
```
  0...1: tSTRING_BEG     => "'"
 1...12: tSTRING_CONTENT => "foobar\\\n"
12...16: tSTRING_CONTENT => "baz\n"
16...17: tSTRING_END     => "'"
17...18: tNL             => nil
```

After:
```
  0...1: tSTRING_BEG     => "'"
  1...6: tSTRING_CONTENT => "foo\\\n"
 6...12: tSTRING_CONTENT => "bar\\\n"
12...16: tSTRING_CONTENT => "baz\n"
16...17: tSTRING_END     => "'"
17...18: tNL             => nil
```
