Abhishek Tripathi d101d6f3de docs: document NOT_FOUND_FUNCTION_BLOB Edge Function error (#48411)
This PR addresses the documentation portion of #47739.

## What the issue means

`NOT_FOUND_FUNCTION_BLOB` means the runtime cannot find the deployed
bundle for an Edge Function. This differs from the existing `NOT_FOUND`
error, which normally indicates that the function name in the request
URL is not recognized.

The dashboard status alone may not reveal this failure because the
function can still appear as `ACTIVE`.

## Changes

- Documented `NOT_FOUND_FUNCTION_BLOB` as an HTTP 404 error.
- Explained how it differs from `NOT_FOUND`.
- Added the command for redeploying one affected function.
- Added the command for redeploying all functions when several are
affected.
- Added guidance to retry the request and contact Support if
redeployment does not resolve the problem.

## Files changed

-
`apps/docs/content/troubleshooting/edge-function-404-error-response.mdx`

## Validation

- The change uses the troubleshooting page's existing TOML frontmatter
and MDX conventions.
- `git diff --check` passes.
