[Feature] Create Error Message if "fields_to_include" is not recognized

### Is there an existing feature request for this?

### Describe the Feature

I was trying to ingest "Quota_ARR__c" from the opportunity into dbt given that it is a formula field in Salesforce. However, no matter what I did, I couldn't get it to work. Despite writing the write syntax (see below), the opportunity table would load, but without "Quota_ARR__c".

` {{
salesforce_formula_utils.sfdc_formula_view(
source_table='OPPORTUNITY',
fields_to_include=['quota_arr__c'],
full_statement_version=false)
}}
`

Because of this, I looked at the Fivetran UI schema to see how it was spelled (which was the same as the way as I wrote it above) & looked at the Salesforce API. However, when I looked at the fivetran_formula table ingested into Snowflake, I saw it was written with 1 underscore rather than 2.

Given this, I highly recommend you create a safeguard that if it is incorrectly written, that the code snippet doesn't run and/or creates an error. I spent hours trying to figure out why this wasn't running until finally realizing it should be 1 underscore, not 2

### Anything else?

_No response_

Start at the sfdc_formula_view entry point and reproduce the example using fields_to_include=['quota_arr__c'] against the formula-field metadata described in the issue. Done means an unrecognized field produces an explicit error instead of silently omitting the field; the issue does not name a file or test to run.
