Warning about unsupported asynchronous Google Analytics

[McPringle]

Describe the bug
When Hugo v0.123.0-3c8a4713908e48e6523f058ca126710397aa4ed5+extended renders my website using Anatole theme v1.13.0 I get the following warning:

WARN  _internal/google_analytics_async.html is no longer supported by Google and will be removed in a future version of Hugo

To Reproduce
Steps to reproduce the behavior:

1. Create a new hugo project:
   hugo new site mytest
2. Enter newly created project:
   cd mytest
3. Make hugo project a module:
   hugo mod init mytest
4. Add Anatole theme as a module:
   hugo mod get github.com/lxndrblz/anatole
5. Add the following lines at the end of hugo.toml:

[module]
  [[module.imports]]
    path = "github.com/lxndrblz/anatole"
    disable = false

6. Create a new post:
   hugo new post/mytest.md
7. Start Hugo server:
   hugo server
8. A warning is shown on the console:
   WARN _internal/google_analytics_async.html is no longer supported by Google and will be removed in a future version of Hugo

Expected behavior
Hugo should start the server using the Anatole theme with default settings without warnings.
