New monitor, Change to existing monitor

🔖 Feature description

It would be nice if we could add a check to verify that a certain cookie is configured the right way. e.g. add checks for a "SID" cookie that the secure flag is set to true or httpOnly is also set to true.
Background:
Due to a framework update we lost these configurations and suddenly the flags were wrong at the cookies. So it would be nice if in such a case Uptime Kuma would alert us. It's also similar to the feature "Monotor SSL Cetificates" wich is already available.

✔️ Solution

It is possible to add one or more cookie checks with a configurable cookie name and add 1 or more properties per cookie which are checked.

❓ Alternatives

Nothing found.

Monitoring cookies is covered in #3568 and I don't see an immediate difference in capability.

In parallel, we are converting the json-query and keyword monitors into generic pieces.
This will make implementing something like #3568 a lot easier.
You can subscribe to/read these issues for further context/intel:

• Proposal: Make Keyword & Json-Query generic across monitor types #3919
• http(s) - header-query #3568
• Add support for custom mongodb commands #4445

We can reopen if you make a good argument why this cannot be covered by a header-query monitor.
