gh-984: Add config to run on Archer2

[connoraird]

Description

• Adds submission scripts and documentation of how to run the regression tests on Archer2.

Testing

• I have tested the archer2 script by running a regression test with fd80e8f as the starting version and main as the final version and received an error due to the change in the glass modules which causes benchmarks for fd80e8f to fail.
• I have also ran comparing main to connor/run-on-archer2 which runs as expected.
