fix(renovate): resolve invalid matchPackageNames and clean up rules (UI5#8691)

Closes UI5#8686

## Summary
- Fix `packageRules[5].matchPackageNames`: drop `"*"` so the negation
pattern is valid — this is the immediate cause of the Renovate
validation failure reported in UI5#8686
- Remove the dead `vite & plugins` rule — its `groupName` was always
overridden by the later root-deps / examples-deps rules, so it had no
effect
- Add `schedule:weekly` and a `groupName` to the MCP server dependencies
rule, matching the convention of the root and examples rules
- Add `semanticCommitType: chore` to the Typescript rule (TS bumps are
tooling, not user-facing fixes)

`ignorePaths` is intentionally retained — it overrides the
`:ignoreModulesAndTests` preset (pulled in via `config:recommended`)
specifically to drop `**/examples/**` from the ignore list, so the
examples/templates/patterns rule can scan those directories.

## Test plan
- [ ] Renovate config validation passes (issue UI5#8686 closed
automatically once Renovate re-validates)
- [ ] Next weekly Renovate run still produces the expected grouped PRs:
  - "all non-major dependencies" for root `package.json`
- "all non-major dependencies (examples, templates & patterns)" for
examples/templates/patterns
- "MCP server dependencies" for `packages/mcp-server/**` (now grouped +
weekly)
- [ ] TypeScript bumps land with `chore(deps):` commit prefix
