Update lexicon workflow is failing

see: https://github.com/tsky-dev/tsky/actions/runs/13460862930/job/37615593706

Also, we could decrease the check frequency as we don't have to keep track of the upstream so fast. (Done by #69)

When handling applyWrites.json, the error is thrown from here:

tsky/packages/lex-cli/src/generator/schema.ts

Lines 97 to 108 in c8ca09a

	if (value.format !== undefined && value.format !== 'uri') {
	if (
	value.maxLength !== undefined ||
	value.minLength !== undefined ||
	value.maxGraphemes !== undefined ||
	value.minGraphemes !== undefined
	) {
	throw new Error(
	`${value.format} format can't be used with length or grapheme constraints`,
	);
	}
	}

where value ===

{
  "type": "string",
  "maxLength": 512,
  "format": "record-key",
  "description": "NOTE: maxLength is redundant with record-key format. Keeping it temporarily to ensure backwards compatibility."
}

The current applyWrites.json:

(I'm not sure but suspect some temporary measure caused a validation error?)
