Unable to detect git repo in 1.37

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Hello,

From your logs:

Run actions/checkout@v2
  with:
    repository: ossf/scorecard
    token: ***
    ssh-strict: true
    persist-credentials: true
    clean: true
    fetch-depth: 1
    lfs: false
    submodules: false

https://github.com/ossf/scorecard/runs/2461368761?check_suite_focus=true

I think that fetch-depth: 1 not enough to create the right diff.

I think you have to do what I have explain here #1088 (comment)

    steps:

      - name: Check out code
        uses: actions/checkout@v2
        with:
          fetch-depth: 0

In v1.37.0 (#1723) we fixed #970: the problem was a silent failure on large git histories.
Maybe before the update, golangci-lint skipped the analysis on your repo.

Thank you! That solves the issue 👍
