Update starlette requirement from ~=0.14.2 to ~=0.15.0 in /src/front

[dependabot]

Updates the requirements on starlette to permit the latest version.

Release notes

Sourced from starlette's releases.

Version 0.15.0

0.15.0

This release includes major changes to the low-level asynchronous parts of Starlette. As a result, Starlette now depends on AnyIO and some minor API changes have occurred. Another significant change with this release is the deprecation of built-in GraphQL support.

Added

• Starlette now supports Trio as an async runtime via AnyIO - #1157.
• TestClient.websocket_connect() now must be used as a context manager.
• Initial support for Python 3.10 - #1201.
• The compression level used in GZipMiddleware is now adjustable - #1128.

Fixed

• Several fixes to CORSMiddleware. See #1111, #1112, #1113, #1199.
• Improved exception messages in the case of duplicated path parameter names - #1177.
• RedirectResponse now uses quote instead of quote_plus encoding for the Location header to better match the behaviour in other frameworks such as Django - #1164.
• Exception causes are now preserved in more cases - #1158.
• Session cookies now use the ASGI root path in the case of mounted applications - #1147.
• Fixed a cache invalidation bug when static files were deleted in certain circumstances - #1023.
• Improved memory usage of BaseHTTPMiddleware when handling large responses - #1012 fixed via #1157

Deprecated/removed

• Built-in GraphQL support via the GraphQLApp class has been deprecated and will be removed in a future release. Please see #619. GraphQL is not supported on Python 3.10.
• The executor parameter to GraphQLApp was removed. Use executor_class instead.
• The workers parameter to WSGIMiddleware was removed. This hasn't had any effect since Starlette v0.6.3.
