`Programs.version` is needed

[h1alexbel]

Currently, we cannot get the version of lints library, without creating the Defect, since it's implementation is package-private (Defect.Simple). Besides that, in some cases it's suboptimal to retrieve only one element from all the received defects to take its .version(). I suggest we introduce new method: version() in Program or Programs in order to do it easier:

final Programs programs = ...;
final String version = programs.version();

This idea was initiated by this: objectionary/eo#3897 (comment)

@yegor256 @maxonfjvipon WDYT?

[h1alexbel]

@maxonfjvipon @yegor256 how about this idea?

[maxonfjvipon]

@h1alexbel I like the idea. Let's do it

[yegor256]

@h1alexbel maybe simply put EOLints-Version into MANIFEST.MF and then read it through com.jcabi.manifests.Manifests.read()?

[h1alexbel]

@yegor256 Yes, my plan was to read version from MANIFEST.MF, the same way we did in Defect.java:

lints/src/main/java/org/eolang/lints/Defect.java

Line 169 in 89a791f

return Manifests.read("Lints-Version");
