Add tests for Schema Evolution on Catalogs

[rambleraptor]

Rationale for this change

PyIceberg is missing a variety of Catalog Tests compared to the Java implementation. This adds 3 different tests for schema evolution to help match the Java library coverage.

Are these changes tested?

Tests should pass.

Are there any user-facing changes?

Just tests.

small nit to format for better readability (if the linter allows it)

Suggested change

	table.update_schema().add_column("col1", StringType()).add_column("col2", StringType()).add_column(
	"col3", StringType()
	).commit()
	table.update_schema()
	.add_column("col1", StringType())
	.add_column("col2", StringType())
	.add_column( "col3", StringType())
	.commit()

The linter deeply does not like this (even with the backslashes to make it syntactically correct)

Please add a test that adds data to a schema after evolution, you will notice it doesn't pick up the latest schema: #2467
