Remove mentions to outdated plugin: cypress-plugin-snapshots

[dwilches]

In this and this pages there are mentions and instructions to install a plugin that has not worked with Cypress since version 4.5.0: cypress-plugin-snapshots.

The first page I mentioned even has instructions to install this plugin:

  // run 'npm i cypress-plugin-snapshots -S'
  // capture the element screenshot and
  // compare to the baseline image

Which if attempted with any recent version of Cypress (> 2020) will give this error:

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: my-project@1.0.0
npm ERR! Found: cypress@12.6.0

npm ERR! 
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

Because of this line in that plugin's package.json:

  "peerDependencies": {
    "cypress": "^4.5.0"
  },

I think there is no purpose on having instructions for a command that won't work if attempted. This Issue is to ask if it can be removed so the next person can focus on visual testing plugins that are maintained.

+1 to this.

The same issue is raised here too: https://github.com/cypress-io/cypress-documentation/issues/5073.
