MINIFICPP-2187 Free up disk space on CI runners for CentOS job

[lordgamez]

To avoid running out of disk space on the centos build job, we can free up space according to these comments:
actions/runner-images#2840 (comment)
actions/runner-images#2606 (comment)

After checking the available disk space before and after removing these directories, I found that we can gain around additional 27GB of disk space with this change:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        84G   65G   19G  78% /

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        84G   39G   46G  46% /

Didnt dwelve into this too much but maybe we could use an off the shelf solution from marketplace? https://github.com/marketplace/actions/free-disk-space-ubuntu

Although it looks better, I think it's a bit simpler and more direct to delete these specific directories, also we don't have to request permission for a new action from Apache.
