fix: checking version was too strict

[lnc3l0t]

In my system I have, for some reasons, a developer version of fzf:

> fzf --version
0.29 (devel)

Although this version meets the minimum required version of 0.29.0 specified by MIN_FZF_VERSION="0.29.0", the check_version function incorrectly fails the check.

This PR addresses the issue by modifying the check_version function. Specifically, the function now allows the version check to pass when the installed version has one fewer segment than the threshold version, provided that the missing segment in the threshold version is 0. For instance, if the threshold version is 0.29.0, then an installed version of 0.29 is considered sufficient, as the trailing 0 does not imply a higher version requirement.

Therefore my additional check

if (( i == ${#threshold_parts[@]} - 1 )) && ((${#ver_parts[@]} == ${#threshold_parts[@]} - 1)) && ((${threshold_parts[i]} == 0));

result in the case tool=0.29 (2 parts) and threshold=0.29.0 (3 parts) and i=2 in

if (( 2 == 3-1 )) && ((2 == 3-1)) && ((0 == 0));

Thanks, I can reproduce the issue as well. I will look into it soon.

This will fail if the user has version 1 and the required version is 1.0.0.

I agree with you @LangLangBart. Your version works for me.

Thank you, I didn't know the bash-variable-default-value syntax ${var:-def}.

Thank you.
