Support .bun-version files

Relates to oven-sh/bun#3917.

It makes sense to use .bun-version instead of .bunv-version, aligning with other popular version managers such as pyenv and rbenv. Plus, Renovate already supports .bun-version for Bun, which further demonstrates the growing adoption of Bun in the ecosystem.

Once this feature is implemented, it will be easier to develop a GitHub Action to setup-bun, similar to setup-node, setup-python, and others.

Do you have an estimated timeline for when this feature might be implemented, if at all?

[aklinker1]

Woops, just a typo. I meant .bun-version, since that's what the GitHub actions supports.

Feel free to open a PR, I don't have any plans on implementing that myself right now. The existing package.json support does everything I need it to do personally.

Should be super easy, already have the structure setup to add support for more files:

Don't know Zig.
Uncommenting is all it takes?

[aklinker1]

Um... maybe? Here's the implementation:

bunv/src/vm.zig

Lines 266 to 278 in 9b1cedc

	const BunVersionFile = struct {
	fn init() VersionFile {
	return .{
	.name = ".bun-version",
	.extractBunVersion = &extractBunVersion,
	};
	}
	fn extractBunVersion(allocator: mem.Allocator, contents: []u8) ?[]u8 {
	return try allocator.dupe(u8, contents) catch |err| switch (err) {
	else => return null,
	};
	}
	};

Looks like the only change is to trim whitespace surrounding the version?

I guess I can do that real quick.

Released in v0.3.2. Re-run the install script to upgrade.

You're awesome @aklinker1!

May you would like to update the Roadmap on the README?

bunv/README.md

- [Support `.bunv-version` files `#8`](https://github.com/aklinker1/bunv/issues/8)

Since I can only install from "official" streams, when Bunv will be available through brew, I could test and share any insights.
