Fix markdown for numbered lists

Checklist:

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

Markdown in
https://argo-cd.readthedocs.io/en/stable/user-guide/config-management-plugins/#debugging-a-cmp leads to hard to read prose.

To Reproduce

Visit https://argo-cd.readthedocs.io/en/stable/user-guide/config-management-plugins/#debugging-a-cmp

The code (on the release-2.5 branch is using 1) instead of 1.:

argo-cd/docs/user-guide/config-management-plugins.md

Lines 259 to 268 in 4bd9f36

	If you are actively developing a sidecar-installed CMP, keep a few things in mind:
	1) If you are mounting plugin.yaml from a ConfigMap, you will have to restart the repo-server Pod so the plugin will
	pick up the changes.
	2) If you have baked plugin.yaml into your image, you will have to build, push, and force a re-pull of that image on the
	repo-server Pod so the plugin will pick up the changes. If you are using `:latest`, the Pod will always pull the new
	image. If you're using a different, static tag, set `imagePullPolicy: Always` on the CMP's sidecar container.
	3) CMP errors are cached by the repo-server in Redis. Restarting the repo-server Pod will not clear the cache. Always
	do a "Hard Refresh" when actively developing a CMP so you have the latest output.

Expected behavior

Numbered lists should be numbered lists instead of jumbled into a paragraph
