do not update the browser's URL on a simple page load

[Lanchon]

when you open a link such as this one:

• https://firmware-selector.openwrt.org/?target=ipq40xx%2Fgeneric&id=linksys_whw03v2

the page immediately rewrites browser's URL adding version=23.05.4& to it. this is a very minor annoyance, but IMHO the page should only modify the browser's URL if the user actually selects something. please consider fixing this.

[mwarning]

The missing version in the link is actually an oversight that was fixed. But I understand that it might be behavior against the norm/expectation. I will fix it if does not complicate the code too much.
