Fix Conda recipe version update in release workflow

[harryswift01]

Summary

Fix the release workflow to correctly update the Conda recipe version before building and publishing to Anaconda.org.

Changes

Fix conda recipe version replacement

• Updated the sed command in the release workflow to correctly match and replace the Jinja version line in conda-recipe/meta.yaml.
• Removed use of extended regex (-E) which caused failures when processing {% ... %} syntax.
• Added a grep check to confirm the version is updated in CI logs.

Impact

• Restores the ability to publish CodeEntropy to the CCPBioSim Anaconda.org channel.
• Prevents release workflow failures caused by invalid regex handling in the Conda recipe.

Looks like this will fix the workflow and an extra grep will make sure that version was updated.
