Added amazon rekognition as a trust endpoint

[pyek-bot]

Description

Adds amazon rekognition url to trusted urls by default preventing user from having to manually add it to use the model.
I have also added (-fips) as an optional string to the regex based on the below link. Please suggest if this seems alright.

Reference: https://docs.aws.amazon.com/general/latest/gr/rekognition.html

Have you tested with making a prediction call if that works?

I tried to create the connector with a rekognition url and it succeeded. I will validate the entire workflow once.

@dhrubo Successfully hit predict api without adding endpoint to trusted urls manually
I also added a test case to validate connector creation.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.x 2.x
# Navigate to the new working tree
cd .worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-3419-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 25e6c9a279df16f4ff1c9a4bcb9e4cf5cd7af91c
# Push it to GitHub
git push --set-upstream origin backport/backport-3419-to-2.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-3419-to-2.x.
