Help with exit-code

Hi, I am using the below workflow which works fine for our use case but, i need the --exit-code to be set to 0 as we don't want to fail the scan or block the PR at the moment, and the scan to succeed.

```
name: gitleaks

on:
pull_request:
branches:
- main

jobs:
scan:
name: gitleaks-try-1
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3

- uses: gitleaks/gitleaks-action@v2
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
GITLEAKS_LICENSE: ${{ secrets.GITLEAKS_LICENSE}}
GITLEAKS_CONFIG: ${{ github.workspace }}/.github/gitleaks.toml
GITLEAKS_EXIT_CODE: 0
```
I checked online on how to pass arguments, but the results were that we cannot do so when we use gitleaks/gitleaks-action@v2 directly.

Kindly help on how to pass the --exit-code=0

Thanks

Start with the workflow shown in the issue and the configuration options for gitleaks/gitleaks-action@v2, focusing on how action inputs or environment variables reach the scan command. Done means the scan still runs while an exit code of 0 prevents the workflow and pull request from failing.
