[MC-305599] Starting from 26.1-snapshot-1, the game version number no longer includes the launcher version (such as HMCL, PCL, etc.)

The JSON of 26.1-snapshot-1 still contains -Dminecraft.launcher.brand=${launcher_name}, and HMCL's launch parameters also include it, so this should be a bug in MC itself.

Environment

Windows 11, version 25H2 (26200.7462) / LibericaJDK-25-Full

Code Before 26.1:

String s = "Minecraft " + SharedConstants.getCurrentVersion().name();
if (this.minecraft.isDemo()) {
    s = s + " Demo";
} else {
    s = s + ("release".equalsIgnoreCase(this.minecraft.getVersionType()) ? "" : "/" + this.minecraft.getVersionType());
}

if (Minecraft.checkModStatus().shouldReportAsModified()) {
    s = s + I18n.get("menu.modded");
}

Code After 26.1:

String versionString = "Minecraft " + SharedConstants.getCurrentVersion().name();
if (this.minecraft.isDemo()) {
    versionString = versionString + " Demo";
}

if (Minecraft.checkModStatus().shouldReportAsModified()) {
    versionString = versionString + I18n.get("menu.modded");
}

The else statement has disappeared.

Also, to clarify, the command-line argument referenced for displaying title here was --versionType, not -Dminecraft.launcher.brand.
