Documentation for proxy is incorrect since the upgrade to WildFly 23

[monzonj]

Describe the bug

The documentation here https://www.keycloak.org/docs/latest/server_installation/#_proxymappings says:

# Configure the proxy-mappings
/subsystem=keycloak-server/spi=connectionsHttpClient/provider=default:write-attribute(name=properties.proxy-mappings,value=[".*\\.(google|googleapis)\\.com;http://www-proxy.acme.com:8080",".*\\.acme\\.com;NO_PROXY",".*;http://fallback:8080"])

But in version 25, value is no longer an array, but a string. This works:

# Configure the proxy-mappings
/subsystem=keycloak-server/spi=connectionsHttpClient/provider=default:write-attribute(name=properties.proxy-mappings,value="[\".*\\.(google|googleapis)\\.com;http://www-proxy.acme.com:8080\",\".*\\.acme\\.com;NO_PROXY\",\".*;http://fallback:8080\"]")

Notice value is now a string and the quotes are escaped.

Version

16.1.0

Expected behavior

Following the proxy configuration documentation should work. instead we get a wildfly error

Actual behavior

We get an error from Wildfly if we follow the documentation

How to Reproduce?
