Fix spacing around inline badges

What does this MR do and why?

Fixes spacing around inline badges when more than one is present.

Regression introduced here: !4395 (merged).

We need to remember we have three kinds of badges:

1. Heading-level badges, added in markdown files.
2. Badges added programmatically to site sections, based on URL path (currently just Contributor and Solutions pages).
3. Inline badges, added in markdown files, but inside paragraphs or tables.

And these rules for combinations:

• Badge types A and C can have multiple badges.
• Badge type B will just have one badge, but it may or may not be rendered alongside badge type A.

When we modify badge styling, we should consider all of these scenarios.

How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Configure a local GitLab Docs environment: https://gitlab.com/gitlab-org/gitlab-docs/-/blob/main/doc/setup.md.
2. Visit pages with various badge combinations (see above for example URLs).
3. Badges should be evenly spaced.
