RF02 issue from (x, acc) in aggregate function
### Search before asking

- [X] I searched the [issues](https://github.com/sqlfluff/sqlfluff/issues) and found no similar issues.


### What Happened

This is more of a question, really. I'm not sure if the issue is with sqlfluff, or if the issue is between the keyboard and the chair. I browsed issues and the web and couldn't find anyone with a similar issue, so I very well could be doing something wrong. I'm getting a linting error RF02 (references.qualification) anytime I'm using an aggregate (or reduce) function. Is there a setting somewhere that I am missing so that these parameters are recognized by sqlfluff as part of the function and not a column of the table?
A couple of example queries included.

### Expected Behaviour

No linting errors within the lambda function when using aggregate

### Observed Behaviour

RF02 (references.qualification) error

### How to reproduce

simple select statement using aggregate(some_column, 0, (acc, x) -> acc + x)

### Dialect

databricks

### Version

sqlfluff, version 3.2.5
python version 3.12.7
dbt-core, dbt-databricks 1.8.5

I am, however, using sqlfluff templater jinja rather than dbt

### Configuration

.sqlfluff:
```yml
[sqlfluff]
# Custom rules
max_line_length = 100

# Supported dialects https://docs.sqlfluff.com/en/stable/dialects.html
# Or run 'sqlfluff dialects'
dialect = databricks

# One of [raw|jinja|python|placeholder]
templater = jinja

# Comma separated list of rules to exclude, or None
# See https://docs.sqlfluff.com/en/stable/configuration.html#enabling-and-disabling-rules
# AM04 (ambiguous.column_count) and ST06 (structure.column_order) are
# two of the more controversial rules included to illustrate usage.
exclude_rules = ambiguous.column_count, structure.column_order, aliasing.table

[sqlfluff:templater:jinja] 
load_macros_from_path = ./macros
```

.sqlfluffignore
```yml
/target/
dbt_modules/
dbt_packages/
macros/
```
