What part(s) of the article would you like to see updated?

YAML treats floats like 2.10 as 2.1. This can lead to workflows using a different language version than intended. We should update the YAML examples to quote language versions to avoid this. To help users who copy-paste-modify without understanding the nuance, we should quote all language versions, even ones that would not be affected by this parsing.

For example:

jobs:
  build:

    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: [3.6, 3.7, 3.8, 3.9]

should be changed to

jobs:
  build:

    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["3.6", "3.7", "3.8", "3.9"]

Then if a user copies the example but wants to include version 3.10, they can easily plug in the new value without knowing they need to add quotes.

Reopening this since some but not all examples have been addressed. Others are welcome to open PRs to partially address this issue as well!
