Add GraphQL for product analytics usage for a group and its projects

What does this MR do and why?

• Adds the ability for project maintainers to get a count of the number of events stored by product analytics per project per month.
• Adds a graphQL interface to enable access to that data.
• Ensure that you're running the devkit with the latest version of the analytics-configurator.
• tidyup Also moves ProductAnalytics::Settings to EE as its unused in CE and shouldn't be there.

Screenshots or screen recordings

Screenshots are required for UI changes, and strongly recommended for all other merge requests.

Before	After

How to set up and validate locally

• Use a project set up for product analytics - ensure some data is stored.
• Run the following query as a maintainer+ on the project:

query {
  project(fullPath: "PATHTOPROJECT") {
      name
      productAnalyticsEventsStored
  }
}

• The result should include the number of events stored that were created in the current calendar month.
• You can also override the month and year parameters:

query {
  project(fullPath: "PATHTOPROJECT") {
      name
      productAnalyticsEventsStored(year: 2023, month: 9)
  }
}
