Allow inexact filtering and filtering by LTS (#4529)

* Allow inexact filtering and filtering by LTS

Right now it is not possible to filter by, e.g. `16`, or `Gallium`.
This would be useful to take a quick glance at just a single major release.
The `"auto"` setting allows for exact matches to be performed by quoting the input, e.g. `"Node.js 16.13.2"`.

* Update static/js/previousVersion.js
