Update "Retrieving issue_token and cookies" Instructions to be more robust

[msirianni]

The problem

Please add to the steps a note that mentions if you are using incognito mode as instructed in step 1, within chrome://settings/cookies you either need to:

• Allow Third Party Cookies (default is "Block third-party cookies in Incognito mode")
  OR
• Add "home.nest.com" and "accounts.google.com" to "Allowed to use third-party cookies" customized list (even if just for the current incognito session)

If you do not, then the login will loop and you won't be able to get the issueToken or Cookie data to show up as expected. You'll know it worked if you were able to login to Nest successfully before completing the steps.

What version of this integration (ha-nest-protect) has the issue?

v0.4.0b2

What version of Home Assistant Core has the issue?

2023.11.2

Thank you for this!

I used the 2nd method and finally got it to work: Add "home.nest.com" and "accounts.google.com" to "Allowed to use third-party cookies" customized list

Thanks both! I hope to have some more time around Christmas / early next year to work on this and make it more robust.

May I advice it's just easier to toggle this switch off here rather than allowlisting cookies?
