Add trailing newline to toc

[dreh23]

The autogenerated TOC has no trailing newline.

This is problematic if you run a markdown linter that lints according to the commonmark spec. Since we autogenerate (adr -u) the TOC and we do linting in a continuous integration context this always fails.

A flag for adr -u to add a newline after generation would be useful.

README.md:3 MD047/single-trailing-newline Files should end with a single newline character

I wonder which tool you are using. This repository does not offer any comamnd line tool(yet). adr-log does not offer -u. Is it our fork of adr-tools? This does not support -u, does it?

I would like to work on a fix, since I also make heavy use of markdown-lint and a GitHub action workflow:

name: Lint
on: [push, pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - name: Set up Git repository
        uses: actions/checkout@v2
      - name: Lint all files
        uses: avto-dev/markdown-lint@v1
        with:
          args: 'en/'
          config: '.markdownlint.yml'

Sorry I think I mixed things up, I am using the npm adr tool from phodal. I filed an ussue there

That motivates me to resume work on adr-j with direct support of MADR.
