Improve weight messaging in `pop call` command

[moliholy]

Few things here:

1. In the Enter the gas limit question:

   • It is not "gas", it's the ref_time component of the weight, i.e. the maximum number of picoseconds of execution for a given extrinsic. The name is misleading, and does not have a 1:1 parallelism with the typical Ethereum "gas" devs are used to. I propose renaming if it to something to "execution time" or something alike. Of course, open to discussion.
   • I wonder... how often users do NOT estimate the call? If users do always estimate, I think it'd make sense to only display this question if the user provides a flag for it, or even in the most extreme case: not specifying it for simplicity.

2. In the Enter the proof size limit question:

   • If the previous question was left blank... will users really fill this one? I think it should be skipped in that case.
   • Same point applies here: it should only be specified if a flag is passed and automatically estimated.

You’re right, we followed the convention used by cargo-contract:

➜  web3project cargo contract instantiate --help
Instantiate a contract

Usage: cargo contract instantiate [OPTIONS] --suri <suri> [FILE]
Options:
     ...

      --gas <gas>
          Maximum amount of gas to be used for this command. If not specified will perform a dry-run to estimate the gas consumed for the instantiation

      --proof-size <PROOF_SIZE>
          Maximum proof size for this instantiation. If not specified will perform a dry-run to estimate the proof size required

  -h, --help
          Print help (see a summary with '-h')

Technically, though, “gas” refers to the combination of both, as explained in the docs: https://use.ink/docs/v6/basics/gas/#what-is-gas-in-ink.

I don’t have an answer here. Personally, I never specify the gas myself. If the user provides it via the command line, we don’t prompt for it, but maybe you are right and we shouldn't even ask for it.

   • If the previous question was left black... will users really fill this one? I think it should be skipped in that case.
     It makes sense to me this improvement.
