[atlassian] Improve scripts

Replace jira and confluence script by a single atlassian-versions script

Also update the atlassian_eol so that:

- Pages are now fetched using Javascript,
- The regex also accept EOS in additional to EOL,
- The full identifier is now required as a parameter (this will make it easier if the name changes again).
