Pull request overview

This PR updates the documentation snippet sources under doc/snippets/ to resolve API doc generation/linking issues (as observed in dotnet/sqlclient-api-docs#94), primarily by fixing xref/cref targets for generic APIs and cleaning up whitespace that can affect rendered docs.

Changes:

• Fix SqlVector type references in SqlDataReader/SqlCommand docs to point to the generic SqlVector<T> (SqlVector\1`).
• Update SqlDataAdapter docs to reference RowUpdating/RowUpdated events (event IDs) instead of the protected OnRowUpdating/OnRowUpdated methods.
• Normalize whitespace/trailing spaces in embedded code examples and lists to avoid formatting noise in generated docs.
