[Bug] guides version dropdown shows latest after selecting older version

[jtolentino1]

Bug

Minor UI bug. On the Guides page, selecting an older version navigates correctly, but the version dropdown still shows the latest version.

Repro

1. Go to https://cryostat.io/guides/
2. Select 1.0.0 from the version dropdown
3. Page navigates to /version/1.0.0/guides/

Actual

Dropdown still shows 4.2.0 - Latest.

Expected

Dropdown should show 1.0.0.

Interestingly, this also means that after you select a different version (ex. 1.0.0), it becomes impossible to re-select the latest version as the dropdown thinks you're already on that latest version. Clicking the Guides nav bar item works.
