Add failing MaintainedApp name to sql error message

[TsekNet]

Problem

#37670 changed docker/darwin to docker-desktop/darwin and broke our CI.

The error MaintainedApp was not found in the datastore is not useful, as it does not identify which app was not found in the datastore, leaving the Fleet admin to try and find what changed recently.

[+] syncing XX policies
[+] syncing XX queries
[+] applying MDM profiles for team XX
[+] applying XX software packages for team XX
Error: applying software installers for team "XX": Resource Not Found: MaintainedApp was not found in the datastore

Potential solutions

Update

fleet/server/datastore/mysql/common_mysql/errors.go

Lines 26 to 37 in cb6260e

	func (e *NotFoundError) Error() string {
	if e.ID != 0 {
	return fmt.Sprintf("%s %d was not found in the datastore", e.ResourceType, e.ID)
	}
	if e.Name != "" {
	return fmt.Sprintf("%s %s was not found in the datastore", e.ResourceType, e.Name)
	}
	if e.Message != "" {
	return fmt.Sprintf("%s %s was not found in the datastore", e.ResourceType, e.Message)
	}
	return fmt.Sprintf("%s was not found in the datastore", e.ResourceType)
	}

to include the name of the app that was not found, not just say MaintainedApp.
