fix(ruby): retrieve devtools version dynamically for package verification

[diemol]

💥 What does this PR do?

The release workflow fails because, at the step where packages are verified to see if they are published, the devtools package in RubyGems is being checked with the wrong version. This PR makes the check use the actual and correct version.

1. devtools_version lacks validation 📘 ☼

Description

devtools_version can return nil when the version file is missing or no matching VERSION line
is found, producing an invalid RubyGems URL in the publish verification step. This violates the
requirement to validate external/config-derived inputs early with clear, actionable exceptions.

Code

rake_tasks/ruby.rake[R12-16]

+def devtools_version
+  File.foreach('rb/lib/selenium/devtools/version.rb') do |line|
+    return line.split('=').last.strip.tr("'", '') if line.include?('VERSION')
+  end
+end

Evidence

PR Compliance ID 13 requires early validation with clear exceptions for external/config-derived
inputs. The added devtools_version reads from a file and returns a parsed value only if a
VERSION line is found; otherwise it implicitly returns nil, and the modified verification URL
interpolates that value without any validation.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`devtools_version` may return `nil` (missing file / missing `VERSION` match), which then gets interpolated into the RubyGems verification URL and causes confusing failures.

## Issue Context
This is a release verification path; failures should be fast and actionable.

2. Duplicate version parsing logic 📘 ⚙

Description

The new devtools_version duplicates the parsing logic already used by ruby_version, increasing
drift risk if parsing rules change. This conflicts with the guidance to centralize shared workflow
logic in tooling/scripts.

Code

rake_tasks/ruby.rake[R12-16]

+def devtools_version
+  File.foreach('rb/lib/selenium/devtools/version.rb') do |line|
+    return line.split('=').last.strip.tr("'", '') if line.include?('VERSION')
+  end
+end

Evidence

PR Compliance ID 16 calls for centralized logic in scripts to prevent drift. The added
devtools_version introduces a second copy of the same line-based parsing approach used by
ruby_version instead of extracting a shared helper.

Best Practice: Learned patterns

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The same version-parsing logic is duplicated in `ruby_version` and the newly added `devtools_version`, which can drift over time.

## Issue Context
This file is tooling/release automation; shared parsing logic should be centralized for reliability.

Pull request overview

Updates the Ruby release verification rake task to check the selenium-devtools gem using its own dynamically-derived version (instead of incorrectly reusing the selenium-webdriver gem version), fixing release workflow package-published verification.

Changes:

• Add devtools_version helper to read the Ruby DevTools gem version from rb/lib/selenium/devtools/version.rb.
• Use devtools_version when verifying the selenium-devtools RubyGems publication URL.
