docs: fix markdown pipe escaping in installation commands

[Mohit-001-hash]

Description

• What changed: Removed the unnecessary backslash escapes (\) from the curl pipe commands in the "Requirements" table of the README.md[cite: 4].
• Why it changed: Including backslashes in these Markdown code blocks can cause the installation commands to fail when users copy and paste them into their terminal, as the shell interprets the backslash literally rather than as a pipe operator[cite: 4].
