Ignore pipes as string starters after `run:` tags

[Svalorzen]

YAML normally uses pipes to delimit multi-line strings. In GitHub actions, however, they are used after run: tags in order to define multiple commands to run. However, even using this plugin, these groups of actions are still highlighted as strings, in other words all in a single color.

It would be nice if this plugin could prevent this behavior and leave general syntax highlighting on for those commands (basically what you'd get if you deleted the pipe symbols from the file).

Example:

run: |
    echo "${{ matrix.os }}"
    echo "string"

Thank you for your report. In my Vim(MacVim), ${{ }} and matrix keyword are both correctly highlighted, as shown in the screenshot below:
