fix(bigquery-jdbc): fix shading exclusions and telemetry credentials (#13515)

b/524234554

This PR fixes two issues in the OpenTelemetry implementation within the
BigQuery JDBC driver:
1. **Shading/Relocation namespace exclusions**: Corrects the API shading
rules to recursively exclude nested OpenTelemetry API subpackages. This
resolves dependency conflicts and `AbstractMethodError` crashes when
client applications inject custom OTel SDK instances.
2. **Telemetry Credentials Resolution bug**: Fixes an
`IllegalArgumentException` thrown when parsing OAuth authentication
types during zero-config credentials initialization.
