fix(fish-deps): filter fish-* tags only; fix starship sh -s flag

git tag --list 'fish-*' replaces for-each-ref so old pre-Rust tags like
pre_whitespace_fix (which have no Cargo.toml) are never selected.

starship update: sh -s -- --yes correctly passes --yes to the piped
install script instead of treating it as a filename for sh to open.
