Ruby 2.5 is EOL

[Sjors]

We should should jump to 2.7 which is supported by Debian Stable aka Bullseye.

https://www.ruby-lang.org/en/downloads/branches/

bitcoincore.org/Gemfile

Lines 3 to 7 in e090689

	## This version should match the version in Debian Stable.
	## If you update the version here, also update it in .ruby-version, .travis.yml
	## and README.md. Then push your branch and make sure Travis supports that
	## version.
	ruby '2.5.5'

Looks like Bundler has now given up on us. https://github.com/bitcoin-core/bitcoincore.org/runs/10582082233:

gem install bundler
ERROR: Error installing bundler:
The last version of bundler (>= 0) to support your Ruby & RubyGems was 2.3.26. Try installing it with gem install bundler -v 2.3.26
bundler requires Ruby version >= 2.6.0. The current ruby version is 2.5.5.157.

The build server now runs latest debian (and refuses to build new website updates until the Gemfile{,.lock} are updated).
