link changelog to dbt-docs for Docs kind

[emmyoop]

resolves dbt-labs/dbt-docs#290

Description

This PR does a few things, all concerning the formatting of changelogs via changie.

1. Links Docs kinds back to dbt-docs instead of somewhat arbitrary issues/PRs within this repo. This is more accurate and will also allow us to automate moving changelogs from dbt-docs into dbt-core.
2. Removes the link to the [CT-388] NO ISSUE #4904 for Kinds Dependency and Security since they are bot PRs with no real issue.
3. Links to the dbt-docs PR in the Contributors section
4. Adds newlines after various sections

Looking good to me!

@jtcohen6 I'd like to know if you're on board with this change and it modifies the format of the CHANGELOG. It's pretty straight forward (no issue for dependency and security PRs + link directly to dbt-docs issues/PRs for Docs changes).

My only question is if security PRs should maybe include the issue if one is present since snyk is not the only thing making security changes?

[jtcohen6]

@emmyoop I'm on board!

[emmyoop]

Great! I made inclusion of the issue conditional for the Dependency and Security types. All other types should have issues associated with them.

[emmyoop]

@McKnight-42 since the adapters don't have the Docs kind it's safe to exclude that part of the logic. But you should update the logic to conditionally include issues for the Dependency and Security kinds. Just opening tickets to do it eventually in each repo would suffice if you don't have bandwidth right now for it.

[McKnight-42]

Just to clarify @emmyoop the addition for the conditional would just be adapter specific versions of this?

[emmyoop]

Exactly! Just adding these new lines into the .changie.yaml for every adapter.

[McKnight-42]

Will add them now, since all the backports will be open will be easy addition great callout.

@jtcohen6 and @leahwicz thoughts on backporting this? It would only involve back porting the .changie.yaml to get the Docs and the dependency and security formatting changes. It's doubtful we would backport docs changes or even dependency changes, but security changes have a high likelyhood. Backporting this seems safer than not and being confused when we backport some security fix and changie balks at the yaml file.
