Update zkvm-vs-zkevm.md

[A-sh2000]

1. In the first sentence, it's better to say "computational tasks" instead of just "computational unit" for clarity.
2. In the second sentence, "zkEVM executes the EVM and produces zero-knowledge proofs to validate their execution." The pronoun "their" seems ambiguous. It's better to specify what is being validated.
3. In the third sentence, "the generated result." should be "the generated results."
4. In the fourth sentence, "Unlike zkEVM, zkVM seamlessly integrates with various computations." It's better to say "Unlike zkEVM, zkVM seamlessly integrates with various computational tasks."
5. In the fifth sentence, "Developers can harness zkVM's framework to create and execute zero-knowledge applications, irrespective of the underlying blockchain network." It's better to specify what kind of applications can be created (e.g., "financial applications") for clarity.
6. In the last sentence, "zkVM finds application in various domains, such as supply chain management, healthcare, and the entertainment industry, where preserving data integrity is imperative." It's better to say "applications" instead of "application" to match the plural form used earlier.
