enable `web/` macros (e.g. `dbt_utils.get_url_parameter()`)

[dataders]

dbt_utils.get_url_parameter() doesn't work currently (neither does get_url_host or get_url_path).

I think it has to do with dbt_utils.split_part:

tsql-utils/macros/dbt_utils/cross_db_utils/split_part.sql

Lines 5 to 9 in 23b11b7

	{% macro sqlserver__split_part(string_text, delimiter_text, part_number) %}
	LTRIM(CAST(('<X>'+REPLACE({{ string_text }},{{ delimiter_text }} ,'</X><X>')+'</X>') AS XML).value('(/X)[{{ part_number }}]', 'VARCHAR(128)'))
	{% endmacro %}

dbt-utils's integration test message is:

('42000', '[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]XML parsing: line 1, character 56, semicolon expected (9411) (SQLMoreResults)')

this was the generated SQL by the integration tests...
