Setting "max-fee" in a profile doesn't work

[barretodavid]

I was able to predefine a lot of flags for the Protostar CLI using profiles in protostar.toml like this:

[profile.testnet.project]
account-address = "0x011088d3cbe4289bc6750ee3a9cf35e52f4fa4e0ac9f42fb0b62e983139e135a"
private-key-path = ".pkey"
network = "testnet"

And then running the command with the profile works

protostar -p testnet invoke \
  --contract-address 0x03c308e8ed89a258d1c5398d81d11fcc2b008b7dc4f7e74fe07d9768d95bb9ef \
  --function "increase_balance" \
  --inputs 10 \
  --max-fee auto

However, if I try to move the max-fee flag to the profile the command fails with the error could not convert string to float: 'auto'

Protostar version

Name	Version
Protostar	0.13.0
Cairo-lang	0.11.1.1
Git	2.39.2

Current Behavior

If I move all the flags, including max-fee to the profile like this

[profile.testnet.project]
account-address = "0x011088d3cbe4289bc6750ee3a9cf35e52f4fa4e0ac9f42fb0b62e983139e135a"
private-key-path = ".pkey"
network = "testnet"
max-fee = "auto"

And then try to execute this command

protostar -p testnet invoke \
  --contract-address 0x03c308e8ed89a258d1c5398d81d11fcc2b008b7dc4f7e74fe07d9768d95bb9ef \
  --function "increase_balance" \ 
  --inputs 10

I get the following error in the terminal:

Traceback (most recent call last):

[21975] Failed to execute script 'binary_entrypoint' due to unhandled exception!

Expected Behavior

The command should be able to execute using all the flags defined in the profile including max-fee

Steps to Reproduce

1. Create a project with protostar init
2. Create a profile for testnet that sets max-fee = "auto"
3. Try to use the CLI for invoke, declare or deploy that expects --max-fee

Possible Solution
