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

@walletconnect/[email protected] is an indirect dependency generated by blade-web3.js (the library to access Blade Wallet extension):

npm list @walletconnect/[email protected]
[email protected] /WS/hedera-mirror-node-explorer-clean
└─┬ @bladelabs/[email protected]
  └─┬ @hashgraph/[email protected]
    └── @walletconnect/[email protected]

We have now moved to using WalletConnect in the Explorer and hence are no longer using the blade-web3.js library.
There should not be any indirect dependency on @walletconnect/[email protected] now.
