$f_First_field depricated in 21.2

[grlicaa]

Since function "$f_First_field" is deprecated in Oracle APEX 21.2
a workaround is added in docs/searchNavMenu.js library

this part of the code will be removed.

This bugfix will be included in the new release coming soon supported from APEX 21.1 version.

For now, as a workaround, you can manually change the JavaScript library inside your plugin. Only (docs/searchNavMenu.js) file.
inside that file issues, 8 - 11 are fixed.
