- configファイルの修正
config/environment/development.rbにてconfig.file_watcher = ActiveSupport::EventedFileUpdateChecker
のコメントアウトで解決したとの記事があった為実施するも変わらず。
【参考】Gemfileのtest・development環境がinstallされない

自己解決
こちらの記事を参考に作業を行ったところ解決しました。
https://unscrupulous-business-firm.com/2022/06/07/ruby-3-1-%E3%81%AB%E3%83%90%E3%83%BC%E3%82%B8%E3%83%A7%E3%83%B3%E3%82%A2%E3%83%83%E3%83%97%E6%99%82%E3%81%AE-unknown-alias-default-psychbadalias-%E5%AF%BE%E5%BF%9C/
以下エラーに注目しました。
Unknown alias: default (Psych::BadAlias)
調べると ライブラリの v3 と v4 で互換性がなくなったことが原因のようです。
config/database.yml
を修正しました。
修正前
adapter,pool,timeoutが共通項目としてdefaultでまとめて設定されています。
default: &default adapter: sqlite3 pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> timeout: 5000 development: <<: *default database: db/development.sqlite3 test: <<: *default database: db/test.sqlite3 production: <<: *default database: db/production.sqlite3
修正後
それを、エイリアスがデフォルト不可となったので以下のように修正しました。
development: adapter: sqlite3 pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> timeout: 5000 database: db/development.sqlite3 test: adapter: sqlite3 pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> timeout: 5000 database: db/test.sqlite3 production: adapter: sqlite3 pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> timeout: 5000 database: db/production.sqlite3
上記修正後、
bundle install git commit -a -m "Update Gemfile for Heroku" git push heroku master
を実行したところ、解決しました。

さらに、URLよりページを開くと以下画面でエラーが表示されましたが
以下記事を参考に
https://zenn.dev/takuty/articles/eadd7eba7a54f0
以下のライブラリをインストールしデプロイするとエラーなく表示されました。
gem 'net-imap' gem 'net-pop' gem 'net-smtp'
