Update dependecy of walletconnect/qrcode-modal for mirror-node-explorer

[hendrikebbers]

As mentioned in #15 we currently depened on walletconnect/[email protected] that shows as LGPL licensed in Snyk. I do not know if it is https://github.com/walletconnect/walletconnect-monorepo or https://github.com/walletconnect/modal but both have way never versions under apache licence. A search at NPM does not show an exact match for the current dependency: https://www.npmjs.com/search?q=walletconnect%2Fqrcode-modal
