feat: make us SEO compatible (#745)

[EtayZaslavsky]

Description

1. Created sitemap.js script. It creates a sitemap file in public/sitemap.xml dynamically from the url paths in the src/routes/index.tsx file. The urls get a static base_url (https://open-bus-map-search.hasadna.org.il/).
2. Added "node sitemap.js" to the build process in package.json.
3. Added the sitemap url to robots.txt.
4. Added a "/" prefix to one of the urls in src/routes/index.tsx, for the sitemap.xml regex to find it (as all other urls had it).
