fix(neovim): LSP, Formatter, Linter all in their places

- Formatter: Don't need both prettier & prettierd. Only use prettierd
- Formatter: markdown-toc is LSP not formatter
- Formatter: shellharden isn't formatter
- Formatter: Only shfmt for shell formatting
- Formatter: Don't need prettier to format yaml
- Linter: codespell on all buffers
- Install script: Remove prettier & shellharden (its useless with bashls)
- LSP: markdownlint, prettier, shellcheck, shellharden, shfmt aren't LSP
