Bug 40787: Plugins buttons misaligned when search box is enabled

The buttons in the plugins home page ("Upload plugin" and "View plugins by class") become misaligned when you have the git repository search bar.

To test:

1. Add a github/gitlab repository in koha-conf.xml
  - In ktd shell, open /etc/koha/sites/kohadev/koha-conf.xml
  - Somewhere under <config> insert the following (or your own)

<plugin_repos>
  <repo>
   <name>Solutions inLibro</name>
   <org_name>inLibro</org_name>
   <service>github</service>
  </repo>
</plugin_repos>

  - Save the file
  - restart_all

2. Go to Administration > Manage plugins
--> Buttons are misaligned

3. Apply the patch

4. Run command « yarn build »

5. Repeat step 2
--> buttons are aligned nicely
