fix: Handle regex values when generating types

[camdecoster]

Description

Update schema type generator to handle regex values in enum attributes.

Closes #8003.

Changes

• Update generator script to use types in place of regex patterns
• Update axis number types to be more permissive (and move them)
• Update generated types

Testing

• Review the generated types and look for regex patterns
  • This can be done with grep in the project root (from the issue): grep -RF "'/^" src/types/generated/schema.d.ts

Notes

• These patterns are valid in the schema, but not in TS
• With no way to use regex to validate a type in TS, it was necessary to build a type that reasonably approximates the pattern (full parity isn't possible because the pattern has no upper bound for the numbers)
• grid.xaxes, grid.yaxes, and grid.subplots were narrowed from any[] to typed arrays. This is correct, but could break some typing for users that used the more general string[] type.
