livecheck: allow query parameter in electron_builder strategy url

[bevanjkay]

This change allows a query parameter to be passed to a URL to a livecheck block using the electron_builder strategy.

This allows the livecheck in Homebrew/homebrew-cask#109152 to return the correct version, as a query parameter of noCache=true or similar needs to be passed to consistently return the latest version.

There may be a better regex to allow the query parameter in the URL.

I did comparative livecheck runs across the casks using ElectronBuilder with/without these changes and the output remained the same (i.e., no unwanted side effects observed).

Additionally, testing this using brew irb works as expected on the URL in Homebrew/homebrew-cask#109152:

irb(main):001:0> Homebrew::Livecheck::Strategy::ElectronBuilder.match?("https://publish.u-tools.cn/version2/latest-mac.yml?noCache=true")
=> true

It probably wouldn't hurt to squash this into one commit but this looks good to me at this point 👍
