Last plugin release date tracker probe

[AayushSaini101]

Description

We need to add a new probe that helps track the release status of the plugin, and how frequently the plugin is released.

Importance:

• Help the Stakeholders to know How long it will take as on average to resolve their issues.
• Time will the difference between the release of the plugin

I don't really think this would produce reliable data because:

• a new maintainer can start to work on a previously abandonned plugin and the average of that plugin would to 10 times the reality
• and the opposite is also true when a maintainer has not enough time to work on a plugin.

This is something we already introduced with

plugin-health-scoring/core/src/main/java/io/jenkins/pluginhealth/scoring/scores/AdoptionScoring.java

Lines 96 to 124 in 7b9a8d6

	new TimeSinceLastCommitScoringComponent() {
	@Override
	public String getDescription() {
	return "There must be a reasonable time gap between last release and last commit.";
	}
	@Override
	public ScoringComponentResult getScore(Plugin plugin, Map<String, ProbeResult> probeResults) {
	final ProbeResult probeResult = probeResults.get(LastCommitDateProbe.KEY);
	if (probeResult == null || ProbeResult.Status.ERROR.equals(probeResult.status())) {
	return new ScoringComponentResult(-100, 100, List.of("Cannot determine the last commit date."));
	}
	final long days = getTimeBetweenLastCommitAndDate(probeResult.message(), plugin.getReleaseTimestamp().withZoneSameInstant(getZone())).toDays();
	final String defaultReason = "There are %d days between last release and last commit.".formatted(days);
	if (days < Duration.of(30 * 6, ChronoUnit.DAYS).toDays()) {
	return new ScoringComponentResult(100, getWeight(), List.of(defaultReason, "Less than 6 months gap between last release and last commit."));
	}
	if (days < Duration.of((30 * 12) + 1, ChronoUnit.DAYS).toDays()) {
	return new ScoringComponentResult(60, getWeight(), List.of(defaultReason, "Less than a year between last release and last commit."));
	}
	if (days < Duration.of((30 * 12 * 2) + 1, ChronoUnit.DAYS).toDays()) {
	return new ScoringComponentResult(20, getWeight(), List.of(defaultReason, "Less than 2 years between last release and last commit."));
	}
	if (days < Duration.of((30 * 12 * 4) + 1, ChronoUnit.DAYS).toDays()) {
	return new ScoringComponentResult(10, 2, List.of(defaultReason, "Less than 4 years between last release and last commit."));
	}
	return new ScoringComponentResult(-1000, getWeight(), List.of("There is more than 4 years between the last release and the last commit."));
	}
	}

and it can be gamified (which is bad) or largely invalid.
