refactor: tree-sitter-nu friendly alternative expressions (#15301)

# Description

Choose more tree-sitter-nu-friendly (if not better) expressions in nu
scripts.
The changes made in this PR all come from known issues of
`tree-sitter-nu`.

1. nested single/double quotes:
https://github.com/nushell/tree-sitter-nu/issues/125
2. module path of `use` command:
https://github.com/nushell/tree-sitter-nu/issues/165
3. where predicates of boolean column:
https://github.com/nushell/tree-sitter-nu/issues/177
4. `error make` keyword:
https://github.com/nushell/tree-sitter-nu/issues/179

Those issues are either hard to fix or "not planned" for syntactical
precision considerations ATM.
