chore(order/bounded_lattice): make `bot_lt_some` and `some_lt_none` consistent (#9180)
`with_bot.bot_lt_some` gets renamed to `with_bot.none_lt_some` and now syntactically applies to `none : with_bot α` (`with_bot.bot_le_coe` already applies to `⊥` and `↑a`).
`with_top.some_lt_none` now takes `a` explicit.
