[FW][FIX] website_sale: non deterministic test failures

[fw-bot]

Wild try to avoid failures on runbot builds (not reproducible locally).

• simplify and split tour steps
• correctly specify check steps as isCheck: true
• make sure python setup is deterministic
  • batch template creation to avoid creation of dummy archived variant
  • target values for the variant to archive instead of its number in the list of variants

runbot build error 25046
