format: replace @import("./foo.zig") with @import("foo.zig")

[fel1x-developer]

@import("./foo.zig") and @import("foo.zig") are equivalent, and ziglang/zig uses @import("foo.zig") in their lib/std since ./ is redundant.

Even in C++, this is not the case. #include "foo.h" is common, whereas #include "./foo.h" is not.

What does this PR do?

• Documentation or TypeScript types (it's okay to leave the rest blank in this case)
• Code changes

How did you verify your code works?

instead of manually fixing this, this type of style thing should be enforced through a linter, or else the problem will just come back.

This cannot be fixed by linter yet because neither zig fmt and vscode-zig's auto-format support this case. I created an issue in ziglang/vscode-zig(ziglang/vscode-zig#379) to support this feature. Until zig or vscode have a feature to format this, we should check manually if the correct syntax is used when reviewing new PRs.

#16366 suggests making a coding style for Bun project, and I have written a section about this.
