[CT-2547] [Bug] dbt docs not finding compiled code with 1.5.0

[gilcrest]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

I currently have 1.4.5 and 1.50 installed via virtual environments. If I run dbt docs generate followed by dbt docs serve using 1.5.0, every model, when I click on the Compiled Code view, has the following message:

Expected Behavior

If I run the exact same commands using 1.4.5, I am able to see the compiled code locally on my dbt docs site.

Steps To Reproduce

I have a really simple shell script that I run in both virtual environments (dbt 1.4.5 and dbt 1.5.0) and I would expect the behavior to be the same and see the compiled sql code on the dbt docs site.

#!/bin/zsh

dbt clean
dbt deps
dbt compile
dbt build
dbt docs generate
dbt docs serve

Relevant log output

@gilcrest Thanks for opening!

The dbt docs serve command currently expects to re-parse the project, and rewrite manifest.json (without the compile step). It really shouldn't do that.

I think we might be able to solve this simply by removing @requires.manifest from the serve task:

dbt-core/core/dbt/cli/main.py

Line 293 in 35f8ceb

@requires.manifest

Let me validate that quickly.
