Add gbraid and wbraid to default mktClickId configuration in campaign attribution enrichment

[adatzer]

Since April 2021 and the release of iOS 14, Google introduced gbraid and wbraid URL parameters to comply with Apple’s transparency policies.

Current behavior Currently campaign attribution enrichment's default mktClickId mappings do not include these parameters, which means that users have to add them in their enrichment configuration or all clicks from Google Ads from an IOS 14 or higher device are not identified as Google Ads.

Expected behavior Mapping these parameters to Google as the mkt_network is included in default mkClickId mappings.
