Support matrix environ badges only with no key-values

After that change:

Are empty values somehow important / do they have an effect on sth?

[xoxys]

Kinda, in this case the plugin config is set dynamically from the matrix env. That means one pipeline is using tag_suffix: "insecure" and another one tag_suffix: "". However, if we want to display empty values, how should they look like?

add an cursive empty ?

[xoxys]

Yes we can do that if we prefer it that way.

[6543]

yes please - as droping it would hide information that the user could need to know for fully understanding what's happening

[xoxys]

Do we want to have the string translated? Or should we use something like null without translations? Translating this string could make it very long.

[anbraten]

We could also avoid the "white" part and make the gray round on the right in case its empty. Would not use an english string in there. If you want a string we could use "-" as well, however that could always lead to someone thinking that's the actual value.

the idea to make a simple lable without the second part is a better idea no need for i18 problems

lgtm based on screenshot
