fix(maven coords): Added in logic to pull Maven coordinates from .fea…

[FezzyBug]

Resolves #14633

The mavenCoordinates attribute has been present on .feature file constituents for some time but was never read or rendered in the generated ESA description HTML.

This change adds a Maven Coordinates section to EsaDescriptionHtmlGenerator:

• Added getMavenCoordinates() — reads mavenCoordinates from each Subsystem-Content constituent, validates the groupId:artifactId:version format, and deduplicates (e.g. grpc-1.0 declares the same coordinate on two jar constituents — these collapse to one rendered block).
• Updated generateDescriptionHtml() — appends a Maven Coordinates section with a <dependency> snippet per unique coordinate, scoped as provided. Section is omitted entirely when no coordinates are declared.

48 public features will now display Maven dependency snippets. Features without mavenCoordinates attributes are unaffected. No runtime behaviour is changed.

---

• I have considered the risk of behavior change or other zero migration impact — additive, documentation-only change to generated HTML. No runtime code, APIs, SPIs, or feature resolution logic are modified.
• This PR resolves Issue Add Maven coordinates to generated feature docs #14633. Not a release bug fix (new enhancement).

Testing was performed locally against the built wlp-generateRepositoryContent.jar.

Unit tests -> EsaDescriptionHtmlGeneratorTest (kept local and not pushed):

• getMavenCoordinates returns the correct deduplicated coordinate list for a feature
  with multiple distinct coordinates
• getMavenCoordinates returns an empty list when no mavenCoordinates attributes
  are declared on any constituent
• getMavenCoordinates deduplicates when two constituents share the same coordinate
  (covers the real grpc-1.0 / grpcClient-1.0 case)
• generateDescriptionHtml emits the Maven Coordinates heading, content div, and
  correctly structured <dependency> blocks when coordinates are present
• generateDescriptionHtml emits no Maven section when no coordinates are declared
• generateDescriptionHtml renders a deduplicated coordinate exactly once in HTML
