docs: fix marketplace name in documentation

[juan-vgv]

Description

The marketplace name is incorrect in the README. Needs updating from very_good_claude_marketplace to very-good-claude-code-marketplace.

Something that is contributing to the confusion is that, as far as I can understand, the name of the marketplace repo uses "_", but the actual name in the market place uses "-".

See here: https://github.com/VeryGoodOpenSource/very_good_claude_code_marketplace/blob/main/.claude-plugin/marketplace.json

PS: I think there's a related issue in the Flutter plugin repo.

The installation will pass with both names but i agree on renaming as it causes confusion. @jorgecoca would be also worth renaming the repo wdyt?

Don't think both work, tried very_good_claude_marketplace and got:

❯ /plugin install vgv-wingspan@very_good_claude_marketplace                                         
  ⎿  Marketplace "very_good_claude_marketplace" not found  

but very-good-claude-code-marketplace worked :)
