[SPARK-30704][INFRA] Use jekyll-redirect-from 0.15.0 instead of the latest

This PR aims to pin the version of `jekyll-redirect-from` to 0.15.0. This is a release blocker for both Apache Spark 3.0.0 and 2.4.5.

`jekyll-redirect-from` released 0.16.0 a few days ago and that requires Ruby 2.4.0.
- https://github.com/jekyll/jekyll-redirect-from/releases/tag/v0.16.0
```
$ cd dev/create-release/spark-rm/
$ docker build -t spark:test .
...
ERROR:  Error installing jekyll-redirect-from:
	jekyll-redirect-from requires Ruby version >= 2.4.0.
...
```

No.

Manually do the above command to build `spark-rm` Docker image.
```
