[BUG] PLEASE BUMP OPTIMIZER VERSION!!!!

[llllllluc]

Recommended solution

Bump optimizer version from 0.12.6 to 0.14.0 or latest.

Issue description

see more detail in my msg in cosmwasm discord

Steps to reproduce the issue

1. Start a new cosmwasm repo, set cosmwasm-std version to 1.4.1 (latest, or any version >= 1.3)
2. Use terrain or terrariums to deploy the code
3. You will see bnum error like below, this is because bnum requires a higher rust version >= 1.65, current version of workspace optimizer use 0.12.6, which use rust 1.6, we need to bump workspace optimizer to 0.14.0 to fix it

   Compiling bnum v0.7.0
   Compiling serde_derive v1.0.189
   Compiling thiserror-impl v1.0.49

    = note: try using `<*const T>::as_ref()` to get a reference to the type behind the pointer: https://doc.rust-lang.org/std/primitive.pointer.html#method.as_ref
    = note: using `<*const T>::as_ref()` on a pointer which is unaligned or points to invalid or uninitialized memory is undefined behavior
    = note: this error originates in the macro `endian` (in Nightly builds, run with -Z macro-backtrace for more info)

Temporary workaround

hardcode cw version to 1.2 cosmwasm-std = "=1.2" so it doesn't contain bnum, this can work with current terrain.

Tools and operating system versions

Please also update terrariums until it's merge it into terrain.
