modify entity, join serializers to allow specify entity() as the on clause predicate.

[sjnqkqh]

Motivation

• Bug when creating a Predicate inside the on() method, using entity() added 'AS [alias]' resulting in syntax error

Modifications

• Add Join, On clause to JpqlRenderClause
• Modified conditional statements to include Join, On clause in EntitySerialiser (so that 'AS alias' is not added when serialising entities in On clause)
• Add code to update JpqlRenderClause to Join, On in FetchJoin, Join, Association join serialisers
• Modify test code according to serialiser modification

• II've changed the base branch from develop to main, but the branch I forked for the fix is line/kotlin-jdsl:develop, in which case would it be better to reference the main branch of line/kotlin-jdsl to do the work and publish the PR?
