Go through all .rst files and update links to pages with local ones

[dernorberto]

Once a Space or a set of .rst files have been downloaded, a script should go through them:

1. collect the page IDs (it's a field value) for ALL available .rst files
2. go through each .rst file, and for every link with the format https://optile.atlassian.net/wiki/spaces/SECOPS/pages/$pagenum ($pagenum being the page ID of the page), replace it with the local link

created https://github.com/dernorberto/confluenceDumpWithPython/blob/main/updatePageLinks.py that does exactly that
