asdf: bug: reshim does not update asdf path

Describe the Bug

jason@Jasons-Work-MacBook-Air ~/f (jax/webpack-quiet)> echo $ASDF_DIR
/opt/homebrew/Cellar/asdf/0.9.0/libexec
jason@Jasons-Work-MacBook-Air ~/f (jax/webpack-quiet)> cat ~/.asdf/shims/dotenv
#!/usr/bin/env bash
# asdf-plugin: ruby 3.0.2
exec /opt/homebrew/Cellar/asdf/0.8.1_1/libexec/bin/asdf exec "dotenv" "$@"
jason@Jasons-Work-MacBook-Air ~/f (jax/webpack-quiet)> asdf reshim ruby
jason@Jasons-Work-MacBook-Air ~/f (jax/webpack-quiet)> cat ~/.asdf/shims/dotenv
#!/usr/bin/env bash
# asdf-plugin: ruby 3.0.2
exec /opt/homebrew/Cellar/asdf/0.8.1_1/libexec/bin/asdf exec "dotenv" "$@"

Might be related to #1103

Steps to Reproduce

Before upgrading to 0.9.0 via homebrew:

1. Install ruby via asdf
2. gem install dotenv
3. Update asdf to 0.9.0 via homebrew
4. Run asdf reshim ruby
5. Path in ~/.asdf/shims/dotenv is still incorrect

Note: Untested

Expected Behaviour

In step 5 the dotenv shim should have the 0.9.0 path

Actual Behaviour

The path in the dotenv shim has the old 0.8.1 path
