Invalid version reference of GitHub Action example in README

[stschaefers]

Bug Description

The README file shows an example how to use the gates GitHub Action. The version reference is consid-germany/[email protected] but it has to be consid-germany/[email protected] because the git version tags are prefixed with v.

gates/README.md

Lines 35 to 48 in 113f2cf

	```yaml
	jobs:
	example:
	permissions:
	id-token: write
	runs-on: ubuntu-latest
	steps:
	- uses: consid-germany/[email protected]
	with:
	gitHubApiBaseUrl: https://github.gates.consid.tech/api
	group: some-group
	service: some-service
	environment: test
	```

To Reproduce

1. Go to https://github.com/consid-germany/gates
2. Scroll down to Quick Start - GitHub Action

Expected Behavior

The GitHub Action example shows a working example with the correct git version tag. We could also think about adding and using a major git tag for the GitHub Action such as consid-germany/gates@v1.

Additional Context

Version @consid-germany/[email protected]
