Update E2Ereadme.md

[LisaMoore01]

What changed? Why?
Before the change, the line was run yarn add -D @playwright/test @coinbase/onchaintestkit. When I copied it and ran it in the terminal, it gave an error. So, for clarity:

• I separated “Run:” and the command
• I wrapped the command in a syntax-highlighted code block (```bash)

Now the copy button copies the working command.

Notes to reviewers

How has it been tested?
Copied the command, it works in the terminal.

Have you tested the following pages?

BaseWeb

• [] base.org
• [] base.org/names
• [] base.org/builders
• [] base.org/ecosystem
• [] base.org/name/jesse
• [] base.org/manage-names
• [] base.org/resources

Nice documentation improvement! Separating the command from the description and using proper bash code blocks makes it much easier to copy-paste.
The copy button functionality is especially helpful for onboarding new contributors to the E2E testing workflow.
