Trade url is wrong (when using trade history)

[Araxeus]

steps to reproduce:

1. go to https://www.pathofexile.com/trade/history
2. click any saved trade
3. the extension forwards to https://www.pathofexile.com/trade/search//mytradehash (indeed with two /) which doesn't exist

it should have instead forwarded to https://www.pathofexile.com/trade/search/Keepers/mytradehash

I opened the issue about the "trade history" tab because its frequently used and where i noticed it, but this issue also affects the "settings" and "about" tabs too

Notes:

1: you might think those tabs don't know which league is currently selected, but check the value of document.querySelector('a[data-target="search"]').href its always the right one

2: the issue is probably that the extension only considers the current url

Lines 113 to 115 in e13d245

	private parseCurrentPath(): ExactTradeLocationStruct {
	const tradeRealms = ['xbox', 'sony', 'poe2'];
	const pathParts = window.location.pathname.split('/').slice(1);

3: I tried fixing it myslef by replacing const pathParts = window.location.pathname.split('/').slice(1); with

 const pathParts = (document.querySelector('a[data-target="search"]')?.href || window.location.pathname.)split('/').slice(1);

but I failed at cloning this repo and running the dev command - i'm getting 1000 warnings about critical vulnerabilities and even when I ignored them like a fool, the build steps still fails... and well im not going to open a pull request for a change i can't test

@dbjorge @pboutin maybe think about updating dependencies (including node and npm required versions from 6 years ago) and making the build step less convoluted and not reliant on gnu utilities for no reason,,, contributing to this repo is way harder than it should be
