Adding Crypto symbols search functionality

[OrganicBeetle]

Project Title

blockchain[OpenTekHub]

Problem Description:

Currently in OpenTekHub, the only search option is to search the full name of the cryptocurrency, like BITCOIN and ETHEREUM only. I have edited the script.js file to allow Searches with the symbols too like, BTC --> BITCOIN ETH --> ETHEREUM SOL --> SOLANA

Need for this fix

Since in the vast pool of cryptocurrencies, a frequent trader would prefer if they could check the prices with only the unique symbols instead of the complete name which coulg get repetitive and time consuming.

Reproducing the Issue

• Visit the deployed website here
• Try Searching for the preferred Crypto using their Symbol (like BTC for BITCOIN)
• Error : "Cryptocurrency not found!"
