fix(schema): fixed linting issues in appsscript.json and asconfig-schema.json

[Vaibhav701161]

Description
This PR addresses schema linting and formatting inconsistencies in the following files:

• appsscript.json
• asconfig-schema.json

The updates focus exclusively on metadata cleanup and stylistic normalization, without introducing any structural or validation changes to the schemas.

• Removed trailing punctuation across multiple description fields to comply with SchemaStore style guidelines.
• Standardized formatting of arrays and object properties to improve readability and consistency.
• Resolved minor lint warnings reported by schema validation tooling.
• Maintained all existing validation rules, references, defaults, and schema semantics.

Before and after:
appsscript.json:

appsscript.json.file.mp4

asconfig-schema.json:

asconfig-schema.json.file.mp4

Note: This PR was generated with assistance from the jsonschema CLI, developed by a member of the JSON Schema TSC. The editor extension used is built on the same CLI.
