Fixes #36584 - Update realtive_path to text in the db from char

[chris1984]

What are the changes introduced in this pull request?

• In Pulp the core_distribution table and column base_path is text without a limit so this PR removes the limit from our DB to match pulp
• This was the approach I worked with Ian on and he said go for it.

Considerations taken when implementing this change?

• I tested with a rhel7 and centos8-stream box and was able to pull content fine, pulp/candlepin were working fine

What are the testing steps for this pull request?

• Create a product with long label name (For example: Community_Extra_Packages_for_Enterprise_Linux_EPEL_debug)
• Create a repository with long label name (Fore example: Community_Extra_Packages_for_Enterprise_Linux_EPEL_8_Modular_x86_64_debug)
• Sync the repository
• Create a content view with label along Community_Extra_Packages_for_Enterprise_Linux_EPEL_8_Modular_x86_64_debug_100000
• Publish

Without PR you should get Error => "Validation failed: Relative path is too long (maximum is 255 characters)"
