Add support for parsing arrays containing values of different types

[iulianbarbu]

Is your feature request related to a problem? Please describe.

This is relevant for supporting patching the runtimeGenesis config with devAccounts like so:

[parachains.genesis.runtimeGenesis.patch.balances]
devAccounts = [
    20000,
    1000000000000,
    "//Sender//{}",
]

Describe the solution you'd like

I'd like the above patch to be applied successfully when starting a network based on a toml containing it, with zombienet/cli.

Describe alternatives you've considered

No response

Additional context

Tried starting some tomls containing the patch above with zombienet/cli in relation to this PR: paritytech/polkadot-sdk#7257, and I reached an error related to different value types in the devAccounts array.
