[5.x]: GraphQL introspection schema gets larger after merging entries

What happened?

Description

Our GraphQL introspection schema is very big after upgrading. Since the merge tools are now available, I tried to merge two entries to see how much that would change the size. But instead of getting smaller, the schema increased in size.

Steps to reproduce

1. Note the size of the introspection schema
2. Merge two entries
3. Note the size of the introspection schema

Expected behavior

Introspection schema reduces in size since there are fewer entries.

Actual behavior

Introspection schema size increases. For example, after merging 3 identical entries with 5 fields, from 40,83MB to 41,38MB

Craft CMS version

Craft Pro 5.3.4

PHP version

8.2.20

Operating system and version

Linux 6.5.0-44-generic

Database type and version

MySQL 8.0.36

Image driver and version

Imagick 3.7.0 (ImageMagick 6.9.11-60)

Installed plugins and versions

• Feed Me 6.3.0
• Redactor 4.1.0
• Redactor Anchors 1.5.0
• SEO v5.0.0-rc5
• Super Table 4.0.2
• Typed link field dev-main
• Webhooks 3.1.0

Start by reproducing the issue on Craft Pro 5.3.4 with PHP 8.2, MySQL 8.0, and the listed plugins. Record the GraphQL introspection schema size before and after merging identical entries; done means merging entries no longer increases the schema size and the behavior is covered by an appropriate regression check.
