[Security Solution] Detection Rules fail to install/update with basic license

[syk-99]

Describe the bug:

Some rules (probably machine learning rules) fail to install/update when basic license is in use.

Kibana/Elasticsearch Stack version:

8.15.3

Server OS version:

Debian and Ubuntu

Original install method (e.g. download page, yum, from source, etc.):

Debian Package from artifacts.elastic.co

Functional Area (e.g. Endpoint management, timelines, resolver, etc.):

Detection Rules

Steps to reproduce:

1. Install Elasticsearch, Kibana (Debian Package)
2. Add Prebuilt Rules
3. Install all Rules (maybe the error happens here as well - could not test with a new setup)
4. Wait for new rules to be available (including machine learning rules)
5. Try to install the new rules

Current behavior:

Some/all ML-rules fail to install - showing a green success-message in the bottom right of the screen "X rules failed to install" without any hint of the cause.
Numbers for installable rules (upgradable rules) increase over time.
Some ML-rules can be enabled even with a basic license in use.

Expected behavior:

All rules should be installable/upgradable regardless of applied license.

Errors in browser console:

Request to
[...]internal/detection_engine/prebuilt_rules/install/_perform
is answered with
"message": "Your license does not support machine learning. Please upgrade your license."
(same behaviour for certain conditions when requesting
[...]internal/detection_engine/prebuilt_rules/update/_perform

Any additional context (logs, chat logs, magical formulas, etc.):
