bug#69655: WARNING: Use of 'load' in declarative module

[chris <chris@bumblehead.com>]

Starting a long time ago, maybe a year ago, I begin seeing this warning screen. The screen appears for a brief moment, after submitting login to wlgreet and before sway desktop is started. I took a cellphone picture of the screen in order to copy the message shown,
```
starting service root...
Service root started
Service root running with value #t.
Service root has been started.
WARNING: Use of 'load' in declarative module (#( gl107)#)  Add #:declarative? #f to your define-module invocation

Some deprecated features have been used.  Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information.  Set it to "no" to supress
this message.
Restarting signal handler.
Now running as process 330.

Succesfully started 2 services in the background
```

Added GUILE_WARN_DEPRECATED="detailed" to my home config results in the messages below,
```
starting service root...
Service root started
Service root running with value #t.
Service root has been started.

Any help or advice is appreciated. Thank you,
