A GitHub Action that purges GitHub's camo image cache so README image updates show up immediately instead of sticking around as the stale cached copy.

## Usage

```yaml

- uses: actions/checkout@v4

- uses: twangodev/camo-buster@v1.0.0

```

By default it scans `README.md`. To scan other files or purge specific URLs:

```yaml

- uses: twangodev/camo-buster@v1.0.0

  with:

    files: |

      README.md

      docs/**/*.md

    urls: |

      https://example.com/badge.svg

```
