Add helm charts

[bredamatt]

This PR adds:

• Dockerfiles for building minimal docker images for each of the binaries (sender, tps, funder)
• Conditional compilation of the binaries based on whether the polkadot-parachain metadata, or rococo-relaychain metadata is used via the usage of feature flags, these are propagated to each crate accordingly
• Refactoring of the n clap argument passed to the binaries to make sure helm templates work
• Helm charts for the tps and sender binaries (these are the ones that will be needed for kubernetes based environments as chain-specs can be used to fund the necessary accounts in advance) based on the DevOps teams' common helm charts
• Some examples to setup local development environments for Kubernetes based deployments independent of zombienet
• Some preliminary tests, which currently do not work (zombienet's later releases may make it work, however), which are related to triggering sTPS on a collator/parachain.
• Also adds GHA pipeline for building docker images on a release for both the tick and rococo metadata accordingly (i.e. two images per binary with different runtime types). Secrets still need to be configured for this to work properly.
• Fixes the GHA tests

Note the sentence "independent of zombienet". I.e. these helm charts are used for deployments in more long-lived, static kubernetes clusters, such as Versi. More work needs to be done to fix this, however, namely:

• fixing the block number which tps starts to scrape from, since this is no longer the second block as per now
• potentially a long living server which continuously exposes sTPS metrics to a long-living Kubernetes cluster

Such tasks are better suited for a different PR so this can be focused on helm and docker related matters.

Looks good @bredamatt 🚀 , small comment (I think typo)
