fish not_found handler shows error if no bins match "mise-"

[jdx]

I believe this needs to be rewritten to use string-match

- (line 65): No matches for wildcard '"mise-"*'. See `help wildcards-globbing`.
    if test "$argv[1]" != "mise" -a "$argv[1]" != "mise-"*
                                                  ^~~~~~~^
in function 'fish_command_not_found' with arguments 'bzl'
in event handler: handler for generic event 'fish_command_not_found'
fish: Unknown command: bzl

this isn't a major bug since the command won't be found anyhow but we should still fix it to remove the noise
