   • I am adding new logging messages
   • I am adding a new telemetry message
   • I am adding new credentials
   • I am adding a new dependency
   • If this is a new feature/behavior, I'm adding the Local Testing parity changes.
   • I acknowledge that I have ensured my changes to be thread-safe. Follow the link for more information: Thread-safe Developer Guidelines

3. Please describe how your code solves the related issue.

Fixed the AST generation where columns where recorded as literals instead of column parameters and parameters were being rearranged in some cases.

Why should col() be removed here? Does it no longer apply to a column reference?

[sfc-gh-vbudati]

So, if you're looking at the original code run:

df29 = df.select(convert_timezone("A", col("B")), convert_timezone(col("A"), "B"), convert_timezone("A", "B"), convert_timezone(col("A"), col("B")), convert_timezone("A","B",None), convert_timezone("A", "B", "A"))

"A" wasn't passed in as a column -- I changed the AST encoder to record what the actual parameter passed in is as opposed to what parameter was given to builtin.
