### What changes were proposed in this pull request?
1. URL encode the `ASF_PASSWORD` of the release manager.
2. Update the image to install `qpdf` and `jq` dep
3. Increase the JVM HEAM memory for maven build.
### Why are the changes needed?
Release script takes hours to run, and if a single failure happens about somewhere midway, then either one has to get down to manually doing stuff or re run the entire script. (This is my understanding) So, I have made the fixes of a few failures, discovered so far.
1. If the release manager password contains a char, that is not allowed in URL, then it fails the build at the clone spark step.
`git clone "https://$ASF_USERNAME:$ASF_PASSWORD$ASF_SPARK_REPO" -b $GIT_BRANCH`
^^^ Fails with bad URL
`ASF_USERNAME` may not be URL encoded, but we need to encode `ASF_PASSWORD`.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
By running the release for branch-2.4, using both type of passwords, i.e. passwords with special chars and without it.
Closes#29373 from ScrapCodes/release-script-fix2.
