A byte index vs char index problem somewhere. |

- closes #5416 Rewrites the `no-control-regex` rule to use a regular expression AST visitor instead of the `regex` crate and parsing by hand. This change simplifies the code and makes it easier to maintain. One notable change in the snapshots is the printing of the control characters. Previously, we always printed from the source text. Now, we print a representation of the control character itself based on its numeric value. This resulted in the nonprintable chars being printed, which are invisible. The other reason for this change is that the spans output by the regex parser for unicode escapes do not match 1:1 when raw strings and escapes are involved. This resulted in goofy looking spans in the output: ``` ⚠ eslint(no-control-regex): Unexpected control character: '*\\x' ╭─[no_control_regex.tsx:1:22] 1 │ new RegExp('\\u{1111}*\\x1F', 'u') · ──── ╰──── ``` Not sure where the bug lies there yet.
