check for advice in addition to checking for completing-read-function having its default value & set more relax url timeout

[nicehiro]

For vertico users who want to use vertico(default completing function) to show biblio candicates, they can check for advice of completing-read-default to avoid using ido-completing-read.

Please check issue https://github.com/cpitclaudel/biblio.el/issues/55

Also, set a more relax url timeout to make sure every url request ok.

Thanks a lot. Would the following check work instead? It only uses public API functions.

(catch 'advised (advice-mapc (lambda () (throw 'advised t)) 'completing-read-default))

Otherwise we can go with your test

(catch 'advised (advice-mapc (lambda () (throw 'advised t)) 'completing-read-default))

This worked and I resubmit it.
