docs: add links to changelog

[alexandear]

This PR adds clickable links to "Since golangci-lint vX.X.0" and "Deprecated since vX.X.0" that point to the appropriate version in the Changelog.

If the version is greater than or equal to v1.44.0, the link should be https://golangci-lint.run/docs/product/changelog/#vXXX. Otherwise, use https://golangci-lint.run/docs/product/changelog/. This is because changelog headings for these versions use the format Month Year instead of vX.X.X.

Deprecated since v2.2.0:

I don't see the interest in pointing to the changelog inside linter/formatter page.

1. For "Deprecated": required information is already inside the page (replacement, reason)
2. For "Since": I don't see the point.

Also, the comparison implementation is bugged.

{{ lt "2/10" "2/2" }} -> true
{{ lt "2/2" "2/10" }} -> false

I implemented an equality because it always works.

In all cases, I think that, at some point, we will remove the v1 elements inside the changelog (because the page is too big and elements related to v1 are useless now).
