Wails doctor reports library of libgtk-3-dev and libwebkit2gtk-4.0-dev incorrectly

Description

I think the contains call in the GO code is too strict when it is looking for the output of "[installed]". The output could be different. For example, in my container Debian bookworm container it shows:

root@091659c6144f:/# apt list -qq libgtk-3-dev
libgtk-3-dev/now 3.24.38-2~deb12u3 amd64 [installed,local]

Thus, I get a false negative.

To Reproduce

Use this dockerfile:

FROM debian:bookworm-slim

ARG GOLANG_VERSION=1.24.1
ARG LLVM_MINGW_URL=https://github.com/mstorsjo/llvm-mingw/releases/download/20250114/llvm-mingw-20250114-msvcrt-ubuntu-20.04-x86_64.tar.xz
ARG NODE_VERSION=20.12.2

doctor should report installed

Additional context

By the way, NPM is installed as the version is seen correctly, however status says not found.

Start with the Wails Doctor dependency checks that parse apt output and report npm status. Reproduce the issue using the provided Debian Bookworm Dockerfile, then compare the parsed results with the shown apt list -qq output and Doctor report. Done means installed GTK/WebKit packages and the installed npm version are reported correctly.
