Docs need some update

[TomVanGreevenbroek]

Hey!

I've tried the workflow and noticed a few fixes you could apply to the Readme.md file 😄

In the example, you are missing the with annotation before the input variables. It should look like this:

      - name: Bit Dependency Update
        uses: bit-tasks/dependency-update@cb70065498a57f855913c2983f45cefa7e16cb0d # v1
        with:
          branch: "master"
          version-update-policy: "semver"

Then, the environment variable BIT_CLOUD_ACCESS_TOKEN should be BIT_CONFIG_ACCESS_TOKEN
