Describe the bug

I have a lot utests that does not work without "via-ir". The compilation with "via-ir" is slow. However, I want to make the compilation a littler faster. I followed ethereum/solidity#12533 (comment) and try to set "yulDetails" in my foundry.toml.

And I followed the foundry-book , and add optimizer_details.yul_details to my foundry.toml:

via_ir = true
[profile.default.optimizer_details]
peephole = false
inliner = false
jumpdest_remover = false
order_literals = false
deduplicate = false
cse = false
constant_optimizer = false
yul = true
[profile.default.optimizer_details.yul_details]
stack_allocation = true
optimizer_steps = ""

Unluckily, the above configuration does not work. The yul_details and its child keys should all be in Camel Case. The working configuration is as follows:

via_ir = true
[profile.default.optimizer_details]
peephole = false
inliner = false
jumpdestRemover = false
orderLiterals = false
deduplicate = false
cse = false
constantOptimizer = false
yul = true

[profile.default.optimizer_details.yulDetails]
stackAllocation = true
optimizerSteps = ""

If the snake case is expected, I think this must be a bug. Or you should update the foundry book.
