fix(docs): pin typescript and tsx majors in examples runner

Unpinned, typescript now resolves to 7.x, which no longer ships
lib/_tsc.js and crashes Yarn 4's builtin compat/typescript patch during
install, failing docs/examples/bootstrap.sh before any example runs.
Matches the existing pin in docs/examples/ts/bootstrap.sh.
