Explore if the `forward` and `backward` commands of the input component should ignore `-` as a word boundary

Currently, Yazi's implementation references nushell, and ignoring - would make Yazi align with bash, something to consider:

• Is this change sensible, i.e. which behavior is more common?
• Besides -, are there any other characters that should be ignored?
• Is there any documentation regarding this behavior (bash mode) for reference?

I don't know what yazi should reference. Albeit, I'd like to point out some cases.

• snake_case: only_one_word I think _ should be ignored and the example captured as only one word
  • I think that's what's expected. Helix, vscode and vim works like that.
• kebab-case: word1-word2-word3 could be 3 words.
  • If counting as 5 words: I think only selection mode would benefit because you could separately select the word between the -
  • If counting as 3 words: Its quicker to cut a word with (ctrl+w)
