Let confix migrate client.toml as well

[julienrbrt]

Like we are extending app.toml with other options, it happens that we are as well extending the client.toml.

For a better user experience, we should allow confix to create the new fields when upgrading SDK version. Confix only supports migrating an app.toml as of now.

Tasks

• Let confix migrate command support an app.toml or client.toml
• Add default client.toml as done for app.toml (https://github.com/cosmos/cosmos-sdk/blob/720890523f41ba4912b9ab33292a74de6093da93/tools/confix/data/) for v0.47, v0.50 and v0.51.
• Update docs

---

          I am going to leave this feature for v0.51 and improve confix to migrate client.toml as well for a better experience.

Hey @julienrbrt , hope you are doing well. I did some work on the change you requested. I'm sure there will be things to change. Can you have a look when you have time? Thanks!

Sure I'll have a look later. Thank you for taking this issue!

Once easy way to test is to try migrating a v0.50 client.toml to latest main (v0.51).

I tested this and it successfully added the gas-adjustment and keyring-default-keyname fields. That's what we are looking for right?
