[CT-1539] [Feature] Ignore manifest.json files for git grep

[dbeatty10]

Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

Problem

There are multiple lengthly JSON files that make it harder to scroll through git grep ... results.

Here is an example file that gums up the results when doing a search like this:

git grep "unrendered_config" tests

Although this JSON file is all text, it's all on a single line which makes it behave more like a binary file for text comparison tools.

Solution

1. Create a .gitattributes file in the root directory
2. Add a line like the following (tweak as needed/desired -- e.g., replace binary with -diff or -text -diff)

   tests/functional/artifacts/data/state/*/manifest.json binary
   

3. Add this line to capture another file that commonly causes overwhelm:

   core/dbt/include/index.html binary
   

Then a command like the following will have more consumable results:

$ git grep "unrendered_config" tests

Binary file tests/functional/artifacts/data/state/v4/manifest.json matches
Binary file tests/functional/artifacts/data/state/v5/manifest.json matches
Binary file tests/functional/artifacts/data/state/v6/manifest.json matches
Binary file tests/functional/artifacts/data/state/v7/manifest.json matches
tests/functional/artifacts/expected_manifest.py:                "unrendered_config": unrendered_model_config,
...

Can we also skip the core/dbt/include/index.html file?

Yeah! Good call @gshank -- added that file name to the description above
