Update ratatui

[nuke-web3]

With ba26a1a I was unable to get cargo install --path . to work, with errors around ratatui. This PR updates deps such that resolution is happy & install is possible without --locked set for local installs at least.

This is a proper (I hope) fix for #2090 🤞

It changes the following:

• cargo update
• Update app to use ratatui 0.26.1 so only one version used in lock file.

Help requested:

make check yields a test fail that I think is a "me" problem with some python requirements missing on my machine:

---- tests::test_pre_commit_py stdout ----
[2024-03-25T23:38:45Z TRACE git2_hooks::hookspath] run hook '"/tmp/.tmpAYKxoe/.git/hooks/pre-commit"' in '"/tmp/.tmpAYKxoe/"'
thread 'tests::test_pre_commit_py' panicked at git2-hooks/src/lib.rs:473:9:
assertion failed: res.is_ok()
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Might CI or a maintainer check if it is just me? 😅 - happy to try and fix it with your help if not.

I followed the checklist:

• added unittests N/A
• I ran make check without errors
• I tested the overall application (unrelated bug I think in Fetch with ssh works, but pull does not. #2158 )
• I added an appropriate item to the changelog N/A

https://github.com/NukeManDan/gitui/commits/tmp/ shows I can indeed sign a gpg commit from a yubikey 🎉 suuuuuper excited this is working now!

please see #2079 and #2100

right now this won't pass CI, you can simlate locally by running make check
