Fix glossary tooltip mismatch

[seokho-son]

To fix #14226. (I found #12608 is related too)

I modified

website/layouts/shortcodes/glossary_tooltip.html

Line 8 in 0fe73a1

{{- $term_info := $glossary_items.GetMatch (printf "%s*" $id ) -}}

from not exact match ("%s*") to exact match ("%s.md").

We can check the current bug in
https://kubernetes.io/docs/reference/glossary/?all=true#term-app-container
If we mouse over to "containers" and "pod", we can check they show wrong tooltips.

We can check the preview as follows,
https://deploy-preview-14227--kubernetes-io-master-staging.netlify.com/docs/reference/glossary/?workload=true#term-app-container

[netlify]

Deploy preview for kubernetes-io-master-staging ready!

Built with commit 48deec2
