[SPARK-33533][SQL] Fix the regression bug that ConnectionProviders do…

…n't consider case-sensitivity for properties

### What changes were proposed in this pull request?

This PR fixes an issue that `BasicConnectionProvider` doesn't consider case-sensitivity for properties.
For example, the property `oracle.jdbc.mapDateToTimestamp` should be considered case-sensitivity but it is not considered.

### Why are the changes needed?

This is a bug introduced by #29024 .
Caused by this issue, `OracleIntegrationSuite` doesn't pass.
