- added test
- added parser g4 in  `extractUrlParameterFunction`
- added visitor logic
- ran spotless
- ran (though will check again once committed and do a full test)
```
cd test/it/parser/
mvn -DskipTests=true generate-sources compile install -q
cd parser/sql/dialect/doris/
mvn test -Dit.test=InternalDorisParserIT
```

 Question
- do we collapse two consecutive changes?
So
```
// DORIS ADDED END
// DORIS ADDED BEGIN
```

would be
```
```
