Make install dir if not present in aptos update revela

[banool]

Description

If the user doesn't already have the default install directory, it would previously fail. Now we make the directory. This is how the Python install script does it.

Test Plan

First delete the default install dir, e.g. for linux ~/.local/bin.

Before:

$ cargo run -p aptos -- update revela
{
  "Error": "Unexpected error: Failed to build self-update configuration: ConfigError: `bin_install_dir` must be a directory"
}

After:

Checking target-arch... aarch64-apple-darwin
Checking current version... v0.0.0
Looking for tag: v1.0.0

revela release status:
  * New exe release: "revela-aarch64-apple-darwin"
  * New exe download url: "https://api.github.com/repos/verichains/revela/releases/assets/155171154"
  * Installing to: /Users/dport/.local/bin

The new release will be downloaded/extracted and the existing binary will be replaced.
