Add goreadme to all-repos.yaml

[alexandregv]

goreadme generates readme file from Go doc. I just made a PR to add pre-commit support to it.

Here is the sample .pre-commit-config.yaml I added as instructions in goreadme's README:

repos:
  - repo: https://github.com/posener/goreadme
    rev: v1.4.2 # Use the latest ref
    hooks:
      - id: goreadme
        entry: env README_FILE=README.md goreadme
        args: ['-badge-goreadme=true', '-badge-godoc=true']

I had to use entry: env README_FILE= because the tool doesn't have a flag for this and won't have it.

In the .pre-commit-hooks.yaml, I used pass_filenames: false because goreadme doesn't rely on staged filenames, it reads the repo for *.go files.

my new repository:

• is added to the bottom or with existing repos from the same account
• contains a license
• is not language: system, language: script, language: docker, or language: docker_image
• does not contain "pre-commit" in the name

appreciate it, but pass_filenames: false is not optimal for the framework so I cannot include these hooks on this page
