docs(skills): quote pip install wrenai[…] consistently

[PaulChen79]

Summary

Two leftover skill files used unquoted pip install wrenai[<extra>] inside backticks. On zsh (the default macOS shell) the unquoted […] is parsed as a glob pattern and the command fails with zsh: no matches found. Every other skill wraps the spec in double quotes; this PR brings the stragglers in line.

File	Change
skills/README.md	pip install wrenai / pip install wrenai[<datasource>] → quoted
skills/wren-generate-mdl/SKILL.md	pip install wrenai[<datasource>] → quoted

This is the follow-up to #2317 — same theme, two stragglers that didn't get touched there.

Test plan

• grep -rnE 'pip install [^"]?wrenai\[' skills/ returns no hits.
• On a fresh zsh shell, pip install "wrenai[memory]" runs without zsh: no matches found.

Walkthrough

This PR quotes pip package names in installation instructions across skills documentation to improve shell compatibility and consistency. The wrenai package and its extras syntax (wrenai[<datasource>]) are now quoted in both the main requirements section and skill-specific prerequisites.

Possibly related PRs

• Canner/WrenAI#2315: The main PR's doc-only tweaks in skills/README.md and skills/wren-generate-mdl/SKILL.md (quoting the pip install "wrenai[<datasource>]" command) build directly on the retrieved PR's broader wren-engine → wrenai rename in the same install-instruction locations.
• Canner/WrenAI#2316: Both PRs update Wren AI documentation around the wren-engine → wrenai rename/migration, including pip install ...wrenai[...] install-command text in README guidance.
• Canner/WrenAI#2317: Both PRs update documentation/skill metadata around the wrenai PyPI package in pip install instructions (main PR adds quoted extras syntax in skills docs, while retrieved PR renames prior wren-engine references to wrenai).

Poem

🐰 With shell-safe quotes, the pip commands now shine,
Package names wrapped in apostrophes fine,
Through skills and through docs, consistency spreads,
A hop and a bound through the install threads!
