fix: sample-queries.txt uses incorrect root field name 'bundles' instead of 'olmbundles'

Summary

The file internal/catalogd/graphql/sample-queries.txt contains several GraphQL query examples that reference the root field name bundles, but the dynamic schema generator derives the field name from the schema name (olm.bundle → olmbundles). As written, those sample queries will fail for users.

Affected lines (approx.)

• Line 82: bundles(limit: 5) {
• Line 121: bundles(limit: 20) {
• Line 145: bundles(limit: 10) {
• Line 163: bundles(limit: 10) {

Suggested fix

Replace all occurrences of bundles( with olmbundles( in internal/catalogd/graphql/sample-queries.txt.

Open internal/catalogd/graphql/sample-queries.txt and inspect the four affected query examples around lines 82, 121, 145, and 163. Compare their root field names with the stated olm.bundle schema naming, update the examples as needed, and verify that no incorrect bundles( references remain.
