`rtx install [email protected]` installs [email protected]* not [email protected].* as expected

[jdx]

this is a hard problem since the fix might break the behavior in unexpected ways. However because we're doing dumb prefix matching, that means [email protected] matches things like 1.10.0 when that's almost certainly not what the user wants.

This can be worked around by doing [email protected]. but ideally that shouldn't be necessary.
