fix: increase lms profile image upload size limit to 2MB

[amits-2u]

JIRA: https://2u-internal.atlassian.net/browse/DOS-6385

Image uploads were failing with “Content too large” errors for files slightly above 1MB.

Although global LMS and CMS NGINX upload limits are higher, the LMS NGINX configuration enforces a stricter, endpoint-level limit for profile image uploads via the EDXAPP_PROFILE_IMAGE_MAX_BYTES setting. This resulted in uploads being rejected before reaching the application.

This change increases EDXAPP_PROFILE_IMAGE_MAX_BYTES from 1MB to 2MB, allowing slightly larger image uploads while preserving the existing endpoint-level protection.

The EDXAPP_PROFILE_IMAGE_MAX_BYTES value has been updated to 2097152 (2MB) in this file, but the corresponding PROFILE_IMAGE_MAX_BYTES setting in docker/build/edxapp/lms.yml is still set to the old value of 1048576 (1MB). This inconsistency could cause profile image uploads to fail in Docker-based deployments while working in other environments. Consider updating docker/build/edxapp/lms.yml line 454 to match this change.
