fix(regex-rule): bugfix for attribute lookup

[dannyibishev]

what

• Added the right attribute lookup logic for the single_header and the single_query_argument blocks of code regarding the regex_pattern_set_reference_statement_rules dynamic block.

  This was done to rectify a misconfiguration and also follows the existing configuration design.

why

• Attribute lookup failed for single_header. The following screenshot was the error I was receiving

│  420:                     name = single_header.value.name
│     ├────────────────
│     │ single_header.value is 1
│
│ Can't access attributes on a primitive-typed value (number).

FYI: Ignore the line number in the nippet. It's from an edited fork of your repo. But this bug does exist here as well
