Health check cannot verify the End of Life date for JIRA

Issue Summary

As part of the Jira health check analysis, the Troubleshooting and Support Plugin checks the support status of a product on today's date and gets Jira's release dates from the MarketPlace.

However, the JSON file returned by the MarketPlace does not contain all Jira releases and we can observe the following messages at the EOL check:
7.6.4: Unable to verify the End of Life date for version '7.6.x'. The check has not been performed.
7.11.2 and beyond: We couldn't verify the End of Life date for JIRA version 7.11.2

Steps to Reproduce

• Using a JIRA 8.10.0 version, access the Admin > System > Troubleshooting and support tools
• At the "Instance health" tab, expand "Supported Platforms" and "End of Life"
• Observe that check was successful and the product had not reached the EOL
• Redo the steps using Jira 8.8.1 version.

Expected Results

• Check was successful and the product had not reached the EOL

Actual Results

• The EOL check was not executed and the following message was presented:
  We couldn't verify the End of Life date for JIRA version 8.8.1.

JSON returned by the Market Place does not contain all the versions

Workaround

Update the troubleshooting plugin to the latest version.
