bug: anchor CLI does not support agave stable versioning

[Arrowana]

Problem:
anchor doesn't support agave install versioning in cli

https://solana.com/docs/intro/installation#install-the-solana-cli
this will install stable-{commit} but this leads to a panic on

anchor/cli/src/lib.rs

Line 638 in afcbaed

.any(|line| parse_version(line) == version);

agave-install list
1.18.18
stable-20a8749f7a71ca230bec4ecdbeb292e3d8cd399d
1.18.26
2.0.19

Workaround: Don't install "stable" and cleanup the folder

Possible fix:

• agave not to install latest stable with this odd folder format but use the release tag
• consuming agave-install list should not panic on non valid version
