chore: remove unused config files

[acuarica]

Description:

This PR cleans up the repo by removing unused files coming from Sourcify.

• .circleci this is used by upstream Sourcify, not us
  .vscode and ui/.vscode unused launch configurations
  tslint.json old lint settings, superseded by .eslintrc.js f855a1c
• services/ipfs unused image, see https://docs.sourcify.dev/docs/repository/#ipfs
  services/s3sync unused image, see https://docs.sourcify.dev/docs/repository/#s3-bucket
  some files from scripts/ that might be used by upstream Sourcify 78c4de9, 93b5dde and ca75ec2
• .github/PULL_REQUEST_TEMPLATE/release.md unused PR template ad266cd
• scripts/hedera-reset-(previewnet|testnet).sh invoke hedera-reset.sh directly from package.json's scripts to avoid indirection and scripts folder pollution 9de95dd
• environments/(build-)?(ipfs|monitor|s3).yaml docker related configs for unused services a61b2eb
• monitor service related files c04daf2
• environments/(grafana|loki-config|promtail-config).yaml satellite service configs 0740bc2
• environments/(repository|server|ui).yaml Hedera compose configs superseded by docker-compose-hedera.yaml b8068f7
• environments/.env.(dev|latest|stable) upstream Sourcify .env config files not used by Hedera 51eed0e
• environments/.env.secrets.gpg unused secrets b3fe100 and related config files 8fa438d
• ui/.env.(development|production) old env var templates and update ui/.gitignore accordingly 99a009a

This PR is a pre-step towards issue #147, where upstream Sourcify images will be consumed directly (except ui).

The ui's landing page is also unused and needs to be removed. However, because removing a page would also require updating the ui/package.json's dependencies, its removal is implemented as part of #160.

Fixes #142.

Notes for reviewer:

The amount of files removed in this PR got larger then I expected. As a recommendation, it might be easier for reviewers to look at each commit individually. Moreover, next to each item is the commit that delete it.

@svienot @rustyShacklefurd I would like your input here, is there something else we should remove?

This looks good.
I guess we might as well get rid of a couple more scripts:

• decrypt.sh
• encrypt.sh
• find_replace.sh
