Feat: installing forge using specific commit should install to different bin dir

[sambacha]

Component

Forge, Cast, Anvil, Foundryup, Chisel

Describe the feature you would like

foundryup: warning: overwriting existing forge in /Users/janitor/.foundry/bin
foundryup: warning: overwriting existing cast in /Users/janitor/.foundry/bin
foundryup: warning: overwriting existing anvil in /Users/janitor/.foundry/bin
foundryup: warning: overwriting existing chisel in /Users/janitor/.foundry/bin

Installing by commit should not overwrite the default install path, in fact foundry should support versioned install paths with a latest path being symlink updated on foundryup updates.

This would allow easier orchestration for regression matrix testing in CI env for example.
