Add chore branch config to GitVersion.yml

This commit updates the GitVersion.yml file to include a new branch configuration for branches matching the ^chore/.*$ pattern. This new configuration ensures that commits to these branches will not alter the tag and are not limited to specific source branches, while also specifying that these commits should result in a patch version increment. For context, the configurations for fix and feat branches are also mentioned, where fix branches are configured similarly to chore branches for patch increments, and feat branches are set up for minor version increments under the same conditions.
