[DOCS] Corrected API path for invalidate token and SSL certificate examples

[lcawl]

Related to #39517

This PR corrects some out-dated examples in the invalidate token API and the SSL certificate API.
It also wraps some long lines of text.

Ideally we can enable the tests on these APIs so that we catch changes like this.

I left some suggestions

Suggestion:

This access token can now be immediately invalidated, as shown in the following example:

[lcawl]

The DELETE examples in the invalidate token API reference don't work in the Kibana Console. They return:

{
"error": {
"root_cause": [
{
"type": "parse_exception",
"reason": "request body is required"
}
],
"type": "parse_exception",
"reason": "request body is required"
},
"status": 400
}

This is related to elastic/kibana#13245

Thus I've marked those examples as //KIBANA to only show the "Copy as curl" link.

[lcawl]

Re-enabling //CONSOLE testing now that elastic/kibana#32407 is merged.
