feat: format @import("./foo.zig") to @import("foo.zig")

[fel1x-developer]

@import("./foo.zig") and @import("foo.zig") are equivalent, but zig's lib/std uses @import("foo.zig") since ./ is redundant. On saving .zig files on vscode, can we make vscode format @import("./foo.zig") to @import("foo.zig")?
