Add paging or sensible page size for GitHub release crawlers

[djesionek]

Reproduction steps

• Use a Jenkins plugin that utilizes tools and provides and "Install from GitHub" option
• The tool has more than 30 released versions returned from GitHub API

---

• execute crawler script locally that uses github API to list releases
• if the github repo has more than 30 releases, only last 30 will be listed in the result

Expected Results

Seing all releases of the said tool.

Actual Results

Only maximum of 30 releases are shown for selection

Anything else?

After checking all crawlers, the following might be affected:

• codeql.groovy
• dependencycheck.groovy (seemingly aware of this issue, only one to mention the "per_page" parameter)
• leiningen.groovy
• sonarqubescannermsbuild.groovy (already submitted PR [sonarqubescannermsbuild.groovy] Added explicit page size to prevent missing releases in the result #137 )
