[SPARK-47144][CONNECT][SQL][PYTHON] Fix Spark Connect collation error by
adding collateId protobuf field
### What changes were proposed in this pull request?
Collated expression `SELECT 'abc' COLLATE 'UCS_BASIC_LCASE'` is failing
when connecting to sever using Spark Connect (in this case with pyspark):
```
pyspark.errors.exceptions.connect.SparkConnectGrpcException:
(org.apache.spark.sql.connect.common.InvalidPlanInput) Does not support convert
string(UCS_BASIC_LCASE) to connect proto types.
```
When using default collation `UCS_BASIC`, the error is not occurring.
Fix the error by making `StringType` protobuf compliant with Spark datatype
which now includes collation id.
### Why are the changes needed?
To fix the error which collations introduce in Spark connect.
### Does this PR introduce _any_ user-facing change?
Yes, when previously running
```
$ ./bin/pyspark --remote 'sc://localhost'
...
>>> spark.sql("SELECT 'abc' COLLATE 'UCS_BASIC_LCASE'")
...
```
the described error would appear. These changes remove the error.
### How was this patch tested?
Changes include test which simulates described behavior by utilizing
`SparkConnectServerTest` to establish client-server connection. Test is invoked
by `build/sbt 'connect/testOnly *SparkConnectServiceE2ESuite'`.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #45233 from nikolamand-db/nikolamand-db/SPARK-47144.
