fix: insufficient conditional branching of shared text URLs

[Robot-Inventor]

When the language is "ja-JP", the URL of the English version of the site is set instead of the Japanese URL.

shadowban-scanner/src/ts/core/sharedTextGenerator.ts

Lines 34 to 37 in a0a6531

	const siteURL =
	navigator.language === "ja"
	? "https://robot-inventor.github.io/shadowban-scanner/"
	: "https://robot-inventor.github.io/shadowban-scanner/en/";
