Gantt PNG export uses ImageMagick's convert command, but it ignores imagemagick_convert_command in configration.yml.

Steps to reproduce:

1. Set incorrect command name (e.g. /usr/bin/_convert) to imagemagick_convert_command in configration.yml
2. Restart Redmine
3. Export gantt to PNG. It should not work because imagemagick_convert_command is wrong, but it works fine.

It seems that you can set the path of Imagemagick's client command to MiniMagick.cli_path.

I created a patch.

I tried this patch on #35424 but that did not fix the issue. Maybe something else is happening, but I'm not enough of a connoisseur :-)

Patch committed, thanks!

The patch can fix some issues when the convert command is not available in the global path, but the binary always must be named convert.

Based on the example from #35424, setting imagemagick_convert_command: /usr/local/bin/convert will generate the following:
  • MiniMagick.cli_path (used for Gantt PNG) will be set to /usr/local/bin and MiniMagick will look after convert binary inside that path.
  • For thumbnail generation, it will be used the exact path from configuration: /usr/local/bin/convert.

In case of a different binary name (convert2 for example), the Gantt PNG will not work.
