fix(init): add reactFeatures to feature display info

Companion change for getsentry/cli-init-api#67. The server now
sends reactFeatures as a known feature for React projects. Add it
to FEATURE_INFO with a human-readable label and hint, and to
FEATURE_DISPLAY_ORDER so it renders correctly in the multi-select
prompt.
