Add template for updating source connector type

[tuliren]

What

• Add new type or update an existing type in the source connector can be complicated because it can affect every destination.
• @alexandr-shegeda, @oustynova, this is the proposed new procedure for any type-related work in the source connector. For each type-related project, we should create an EPIC according to the template.

How

• Add test case first in the destination acceptance test (DAT).
• Make sure that all the destinations can read the new type. Or at least they will not break.
• Verify that all destination can pass the new DAT test case.
• Update source connectors to support the new type as the last step.

I have updated this issue to adopt this template as an example: #8904

this is for adding support for new types in the Airbyte type system? what's an example for how it would be used?

This is what we talked about on Monday. It is not just adding new types, but also for updating an existing type. An example is to change the timestamp precision from second to millisecond.
