Adds WEB_NEXT_SENTRY_DSN, NEXT_PUBLIC_WEB_NEXT_SENTRY_DSN, CMS_SENTRY_DSN,
WEB_TANSTACK_SENTRY_DSN, VITE_WEB_TANSTACK_SENTRY_DSN, VITE_GIT_COMMIT_SHA,
SENTRY_AUTH_TOKEN, SENTRY_ORG, SENTRY_PROJECT_{WEB_NEXT,CMS,WEB_TANSTACK},
SENTRY_TRACES_SAMPLE_RATE, SENTRY_ENVIRONMENT, VERCEL_GIT_COMMIT_SHA,
NEXT_PUBLIC_VERCEL_GIT_COMMIT_SHA, and VERCEL_ENV.
