To rewrite as you wish use the following text and duplicate it with the good argument each time i.e :

RewriteCond %{QUERY_STRING} ^url_query=my-article$ RewriteRule ^page$ https://www.website.com/page/my-article? [R=301,L]

Or with automation

RewriteCond %{QUERY_STRING} url_query=(.) RewriteRule ^(.)/url_query=$ $1?page=%{QUERY_STRING} [R=301,L]

R=301 : Type of redirection permanent means after SEO and all stuf you will "maybe" delete the old url. In any case the good url is this one ...

Have a good day...
