lib/history: remove redundant export for HISTIGNORE #501

Closed akinomyoga closed 6 months ago

There does not seem to be a specific reason that we export HISTIGNORE as mentioned in https://github.com/ohmybash/oh-my-bash/discussions/500#discussioncomment-7676355. These lines were introduced in commit 53fb8037 but only HISTIGNORE had export.

In this PR, I try to remove the redundant export from the definition of HISTIGNORE. I'll wait for a while. If anyone has a reason to export HISTIGNORE, please let me know in this PR.
