Updates to database bootstrapper Lambda do not re-trigger the function

[hrodmn]

I recently deployed a PgstacDatabase and discovered that even though the bootstrapper code had changed, the bootstrap script did not get re-triggered like I expected. I think this is because the CustomResource that triggers the function will only run if one of its properties changes.

eoapi-cdk/lib/database/index.ts

Lines 114 to 123 in 9224d0a

	let customResourceProperties : { [key: string]: any} = props.customResourceProperties ? { ...defaultPgSTACCustomOptions, ...props.customResourceProperties } : defaultPgSTACCustomOptions;
	// update properties
	customResourceProperties["conn_secret_arn"] = this.db.secret!.secretArn;
	customResourceProperties["new_user_secret_arn"] = this.pgstacSecret.secretArn;
	// if props.lambdaFunctionOptions doesn't have 'code' defined, update pgstac_version (needed for default runtime)
	if (!props.bootstrapperLambdaFunctionOptions?.code) {
	customResourceProperties["pgstac_version"] = DEFAULT_PGSTAC_VERSION;
	}

Maybe we could add a property with a hash from the contents of the bootstrapper_runtime that would force the bootstrapper to run again.
