Encode when migrating ProcessCommitWorker jobs

This adds encoding logic to the migration for ProcessCommitWorker, ensuring it doesn't throw errors when the input can not be converted to UTF-8 without extra help.

Fix broken link for latest deployment

## What does this MR do?

Creates a new helper for the latest deployment link.

A helper that returns a link was being called inside another helper that creates a link, resulting in  `builds/<a href="builds/ID>#id</a>`

## What are the relevant issue numbers?

Closes #25136

See merge request !7839

See merge request !8066

Adds the ability to cherry pick a commit via the API. Right now it only supports to directly cherry pick a commit and not starting a MR from it. Shall we do that also for the API?

Closes #25450

See merge request !8047

For single line Git commit messages, the close quote should be on the same line as the open quote

_Originally opened at !7299 by @jzinn._

- - -

## What does this MR do?

Chomps merge commit messages so that there is not a dangling close quote.

A better solution would be not to use quotes at all, but to set off the message in a `<div>` with a background color.

## Screenshots (if relevant)

API: Ability to get group's project in simple representation

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/25412

See merge request !8060

If the source encoding is not UTF-8 we need to encode the data as
`JSON.dump` may throw an error if the input can not be converted to
UTF-8. We only encode when necessary to reduce the overhead.

Fixes gitlab-org/gitlab-ce#25489

Adds changelog

Add index to routes table on lower path for postgresql
