Fix grammar: remove misused 'set up' noun in Copilot Spaces prerequisites

[cytustse-cmd]

Why:

On /copilot/how-tos/provide-context/use-copilot-spaces/use-copilot-spaces, the prerequisites list reads:

Configure the set up of the remote GitHub MCP server so that the Copilot Spaces toolset is enabled.

"Set up" is a verb phrase; the noun form is "setup". The wrapper phrase is also redundant — the configuration is the setup. Removing "the set up of" makes the sentence grammatically correct and more concise, and matches the style of the first bullet immediately above it ("Set up the remote GitHub MCP server for your IDE").

What is being changed:

Single-line copy fix in content/copilot/how-tos/provide-context/use-copilot-spaces/use-copilot-spaces.md:

• Before: Configure the set up of the remote GitHub MCP server so that the Copilot Spaces toolset is enabled.
• After: Configure the remote GitHub MCP server so that the Copilot Spaces toolset is enabled.

No links, structure, or technical instructions changed.

Check off the following:

• Pure copy fix; rendered output differs only in the edited sentence.
• I have completed the self-review checklist.
