fix: unable to use OO 8.2 with arabic language - EXO-76393

Before this fix, when the platform is configured in arabic we are unable to open OO for a document
This is due to collation problem on column EDITOR_PAGE_LAST_MODIFIED : OO send last modidied date in arabic, which cannot be store with latin1 charset

This commit update the charset for this column
