Fix identifier quoting in postgresql_publication resource

[myzktkyk]

Description

Fixes #577

This PR adds proper identifier quoting using pq.QuoteIdentifier() for publication names and owner names in all SQL statements within the postgresql_publication resource.

Problem

When setting a publication owner or name containing special characters (e.g., hyphens like tenant-management-user), the resource failed with a syntax error:

Error: could not update publication owner: Error updating publication owner: pq: syntax error at or near "-"

This occurred because identifiers were not properly quoted in SQL statements.

Solution

Added pq.QuoteIdentifier() to all publication and owner name references in:

• CREATE PUBLICATION statements
• ALTER PUBLICATION ... OWNER TO statements
• ALTER PUBLICATION ... ADD/DROP TABLE statements
• ALTER PUBLICATION ... SET statements (parameter updates)

This aligns the publication resource with the identifier quoting standards already implemented in other resources (database, schema, role, etc.).

Testing

• ✅ All publication acceptance tests pass, including TestAccPostgresqlPublication_UpdateOwner and TestAccPostgresqlPublication_UpdateName
• ✅ Tests now validate identifiers with hyphens work correctly
