Docs: Update dev.yml file example for GitHub Actions versions

[mjbear]

Hello Arista Engineering people,

:bulb: In the markdown there is an example for dev.yml that needs updated. The rest of this will be placed in an issue over in the main AVD repository.

I still had some time on the temporary ATD lab environment and couldn't resist working through the CI/CD section! In going through that section I discovered that GitHub has made some changes to supported versions of Node.js so some versions of GitHub Actions need adjusted.

Please test that you too have issues with the GitHub Actions at the pinned versions the lab uses. :arrow_right: I'd be glad to submit a PR after receiving your blessing. Thank you!

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3, actions/setup-python@v3, actions/cache@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

In dev.yml I made the following changes:

uses: actions/checkout@v3 >> v4

uses: actions/setup-python@v3 >> v5

uses: dorny/paths-filter@v2 >> v3
(in two locations)

In prod.yml I made the same changes as dev:

uses: actions/checkout@v3 >> v4

uses: actions/setup-python@v3 >> v5

uses: dorny/paths-filter@v2 >> v3
(in two locations)

Additionally I've opened up an issue and eventually a PR against the aristanetworks/ci-workshops-avd repository.

I've been meaning to do this for a while. Great find, please go ahead and submit a PR. Please make sure to update the docs repository (this one) and the ci fundamentals repo. Great to see you went through the CICD sections, not many take the challenge :)

I've updated the ci fundamentals via this PR 89 within that repo

I'm working on a PR for the lab docs (this repo).
