gh: Increase the maximum word limit for commit message body

[Tim-Zhang]

The original limit 72 was too strict to follow.

Wrapping at 72 columns is fairly standard for git commit messages, it doesn't seem like a big issue to me. Is there something you can't wrap?

I usually come across the limit (in other repos) when adding a link for context as they easily go over 72 characters.

As an example, this link is 133 characters: https://github.com/rust-vsock/tokio-vsock/pull/58/files#diff-dc1d1c7a5a92959296d3eee0db74d0ba440ff9c6ba8cdcebde10091bdd00ab8fR51-R52
