fix(hex/mix): stop suffixing versions with == by default

[kivra-pauoli]

Changes

Semantic versions (not ranges) in mix.exs files stop getting suffixed with == , by default.

Context

0c06a23#diff-5050def58eaa9d548349c16252d28f932eb05401d5981e867392517f18c18847R80 introduced == as an always-present suffix to hex versions (Hex and Git alike). The problem that comes with this (up until now we'd been updating our PRs "by hand") is that e.g. a dependency like {:k_lib, git: "[email protected]:k/k_lib.git", tag: "v0.0.1"} gets updated to {:k_lib, git: "[email protected]:k/k_lib.git", tag: "== v0.0.2"} which is not valid Mix syntax.

I was looking at the code and trying to do this optionally but I can't seem to find (does it exist?) a proper option... if I could pass something from mix to hex then I could use that to optionally add the == , keeping previous behaviour but allowing for the bug fix.

How I've tested my work (please select one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or

We could also do

    if (currentValue.startsWith("== ") && npm.isVersion(newSemver)) {
      newSemver = `== ${newSemver}`;
    }

or similar, where the == would only be added if it was there in the first place, which would also be less surprising.
